From Denial to Acceptance: How the Confederacy Came To Terms with the American Civil War

This thesis seeks to answer one of the fundamental questions of history: how did the people, in a given place and time, view their world? This work addresses Confederates, or those Southerners who supported the secession movement and the Confederate States of America, during the American Civil War, 1861-1865. This work seeks to offer a nuanced view into the minds of Confederates over the course of the war by framing their experience with the Five Step Grieving Process. This process, first described by psychiatrist Elizabeth Kubler-Ross, identifies the five major emotions a person experiences while suffering a loss. These emotions are denial, anger, bargaining, depression and acceptance. This framework allows greater insight into the Confederate culture because it does not force people’s lived experiences into a cause, process, effect format. Instead, it allows flexibility in understanding the human condition as many different people faced the loss of a way of life. The five stages of the Grieving Process provide the structure for this thesis. Research rooted in the diaries, letters, newspapers, and sermons of Confederates allows their lived experience, told in their own words, to illustrate the usefulness of the five-step grieving process as an analytical framework. This approach brings together voices from women, men, soldiers, civilians, government officials and journalists from across the Confederacy. Class lines and geographical boundaries only enhance the efficacy of the framework as the Confederates worked toward accepting the doom of the American Civil War

The Clusters AgeS Experiment (CASE). II. The Eclipsing Blue Straggler OGLEGC-228 in the Globular Cluster 47 Tuc

We use photometric and spectroscopic observations of the eclipsing binary OGLEGC-228 (V228) to derive the masses, radii, and luminosities of the component stars. Based on measured systemic velocity, proper motion and distance, the system is a blue straggler member of the globular cluster 47 Tuc. Our analysis shows that V228 is a semi-detached Algol. We obtain M=1.512 +/- 0.022 Msun, R=1.357 +/- 0.019 Rsun, L=7.02 +/- 0.050 Lsun for the hotter and more luminous primary component and M=0.200 +/- 0.007 Msun, R=1.238 +/- 0.013 Rsun, L=1.57 +/- 0.09 Lsun for the Roche lobe filling secondary.Comment: 19 pages, 5 figures, AJ, in pres

Radial Velocity Studies of Close Binary Stars.VIII

Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for the seventh set of ten close binary systems: V410 Aur, V523 Cas, QW Gem, V921 Her, V2357 Oph, V1130 Tau, HN UMa, HX UMa, HD 93917, NSV 223. All systems, but three (V523 Cas, HD 93917, NSV 223), were discovered photometrically by the Hipparcos mission. All systems are double-lined (SB2) binaries and all, but the detached, very close system V1130 Tau, are contact binaries. The broadening-function permitted improvement of the orbital elements for V523 Cas, which was the only system observed before for radial velocity variations. Spectroscopic/visual companions were detected for V410 Aur and HX UMa.Comment: AASTeX5, 4 figures, 3 tables, to appear AJ, June 200

Radial Velocity Studies of Close Binary Stars. IX

Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for the eighth set of ten close binary systems: AB And, V402 Aur, V445 Cep, V2082 Cyg, BX Dra, V918 Her, V502 Oph, V1363 Ori, KP Peg, V335 Peg. Half of the systems (V445 Cep, V2082 Cyg, V918 Her, V1363 Ori, V335 Peg) were discovered photometrically by the Hipparcos mission and all systems are double-lined (SB2) contact binaries. The broadening function method permitted improvement of the orbital elements for AB And and V502 Oph. The other systems have been observed for radial velocity variations for the first time; in this group are five bright (V<7.5) binaries: V445 Cep, V2082 Cyg, V918 Her, KP Peg and V335 Peg. Several of the studied systems are prime candidates for combined light and radial-velocity synthesis solutions.Comment: 17+ pages, 2 tables, 4 figure

Varón joven con insuficiencia cardíaca derecha e hipertensión pulmonar

A 33-years old man with previous non-controlled hyperthyroidism was admitted to the hospital because of right-sided heart failure. In a transthoracic echocardiography (TTE) a moderate pulmonary hypertension (PH) and dilatation of the right chambers were detected. We ruled out left-sided heart failure, lung, thromboembolic, autoimmune or infectious diseases and portal hypertension. The patient received beta blockers, digoxin and carbimazole at high doses. Concurring with the normalization of the thyroid function the following TTEs showed reduction of the pulmonary artery pressure and right chambers diameter. Identifying hyperthyroidism as a cause of PH has important implications in its management and prognosis.Varón de 33 años con hipertiroidismo no controlado que ingresó por insuficiencia cardíaca descompensada de predominio derecho objetivándose en ecocardiografía transtorácica (ETT) hipertensión pulmonar (HTP) moderada y dilatación de cavidades derechas. Descartados el fallo cardíaco izquierdo, enfermedad pulmonar y enfermedad tromboembólica crónica, enfermedades autoinmunes o infecciosas o hipertensión portal, recibió tratamiento con betabloqueantes, digoxina y carbimazol a altas dosis. Paralelo a la normalización de la función tiroidea se objetivó en ETT seriadas disminución de la presión de la arteria pulmonar y tamaño de las cavidades derechas. Identificar al hipertiroidismo como causa de HTP es importante por las implicaciones terapéuticas y el buen pronóstico en comparación con otras causas de la misma

Radial Velocity Studies of Close Binary Stars.VI

Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for the sixth set of ten close binary systems: SV Cam, EE Cet, KR Com, V410 Cyg, GM Dra, V972 Her, ET Leo, FS Leo, V2388 Oph, II UMa. All systems except FS Leo are double-lined spectroscopic binaries. The type of FS Leo is unknown while SV Cam is a close, detached binary; all remaining systems are contact binaries. Eight binaries (all except SV Cam and V401 Cyg) are the recent photometric discoveries of the Hipparcos satellite project. Five systems, EE Cet, KR Com, V401 Cyg, V2388 Oph, II UMa, are members of visual/spectroscopic triple systems. We were able to observe the close binary system EE Cet separately of its companion, but in the remaining four systems we could separate the spectral components only through the use of the broadening-function approach. Several of the studied systems are prime candidates for combined light and radial-velocity synthesis solutions.Comment: AASTeX5, 5 figures, 2 tables, modified after the AJ revie

Observations of the pulsating subdwarf B star Feige 48: Constraints on evolution and companions

Since pulsating subdwarf B (sdBV or EC14026) stars were first discovered (Kilkenny et al, 1997), observational efforts have tried to realize their potential for constraining the interior physics of extreme horizontal branch (EHB) stars. Difficulties encountered along the way include uncertain mode identifications and a lack of stable pulsation mode properties. Here we report on Feige 48, an sdBV star for which follow-up observations have been obtained spanning more than four years, which shows some stable pulsation modes. We resolve the temporal spectrum into five stable pulsation periods in the range 340 to 380 seconds with amplitudes less than 1%, and two additional periods that appear in one dataset each. The three largest amplitude periodicities are nearly equally spaced, and we explore the consequences of identifying them as a rotationally split l=1 triplet by consulting with a representative stellar model. The general stability of the pulsation amplitudes and phases allows us to use the pulsation phases to constrain the timescale of evolution for this sdBV star. Additionally, we are able to place interesting limits on any stellar or planetary companion to Feige 48.Comment: accepted for publication in MNRA
