Very Massive Stars and the Eddington Limit

We use contemporary evolutionary models for Very Massive Stars (VMS) to assess whether the Eddington limit constrains the upper stellar mass limit. We also consider the interplay between mass and age for the wind properties and spectral morphology of VMS, with reference to the recently modified classification scheme for O2-3.5If*/WN stars. Finally, the death of VMS in the local universe is considered in the context of pair instability supernovae.Comment: 6 pages, 4 figures, from "Four Decades of Massive Star Research" (Quebec, Jul 2011), ASP Conf Ser, in press (L.

A Kingdom Divided: Evangelicals, Loyalty, and Sectionalism in the Civil War Era

Even as the Civil War still raged, interested observers knew that religion had brought on and sustained the conflict, a view that a trove of more recent scholarship has sustained. In more recent years, Civil War era scholars have turned to studying the border between the United States and the Confederate States to further elucidate the nature of union and secession in ways that complicate a simpler binary of north versus south. Holm’s splendid monograph combines these two vital areas of study revealing many important and ironic ways in which border religion at once sought to mitigate disunion impulses, but then nurtured both sectional separation and continued ecclesiastical disunion long after Appomattox

Upon the Altar of the Nation: A Moral History of the Civil War

What Constitutes an Just War? Morality and the Civil War An ambitious undertaking, Stout attempts to apply the evolving concept of just-war theory, especially in examining the actual conduct of war, to fashion a moral history of the Civil War. His question then is not how the wa...
