Photometric and spectroscopic variability of the FUor star V582 Aurigae

We carried out BVRI CCD photometric observations in the field of V582 Aur from 2009 August to 2013 February. We acquired high-, medium-, and low-resolution spectroscopy of V582 Aur during this period. To study the pre-outburst variability of the target and construct its historical light curve, we searched for archival observations in photographic plate collections. Both CCD and photographic observations were analyzed using a sequence of 14 stars in the field of V582 Aur calibrated in BVRI. The pre-outburst photographic observations of V582 Aur show low-amplitude light variations typical of T Tauri stars. Archival photographic observations indicate that the increase in brightness began in late 1984 or early 1985 and the star reached the maximum level of brightness at 1986 January. The spectral type of V582 Aur can be defined as G0I with strong P Cyg profiles of H alpha and Na I D lines, which are typical of FU Orionis objects. Our BVRI photometric observations show large amplitude variations V~2.8 mag. during the 3.5 year period of observations. Most of the time, however, the star remains in a state close to the maximum brightness. The deepest drop in brightness was observed in the spring of 2012, when the brightness of the star fell to a level close to the pre-outburst. The multicolor photometric data show a color reversal during the minimum in brightness, which is typical of UX Ori variables. The corresponding spectral observations show strong variability in the profiles and intensities of the spectral lines (especially H alpha), which indicate significant changes in the accretion rate. On the basis of photometric monitoring performed over the past three years, the spectral properties of the maximal light, and the shape of the long-term light curve, we confirm the affiliation of V582 Aur to the group of FU Orionis objects.Comment: 9 pages, 8 figures, accepted for publication in A&

A Writing Revolution: Using Legal Writing\u27s \u27Hobble\u27 to Solve Legal Education\u27s Problem

The attached article responds to a 2011 article by John Lynch, published in the Journal of Legal Education, that urged legal writing faculty to return to an outmoded and ineffective writing pedagogy, the “product approach,” on the grounds that it would make teaching legal writing easier. This article builds on the work of Carol McCrehan Parker and others interested in writing across the curriculum and argues that the only way to reduce legal writing’s “hobble” and to solve legal education’s problem is to create a six-semester writing requirement. The reason law students are graduating without adequate preparation for practice is that law schools have failed to commit to teaching writing. Most law students graduate having been required to take only an introductory course that teaches practice-related writing skills and an upper-class seminar with a scholarly writing requirement. Law schools can no longer afford to rely on a small percentage of faculty or externships to teach the most important skill law students have to offer on graduation. Because matriculating students have less writing skill and experience than they did even a decade ago, the need for a six-semester writing requirement is that much greater. This article then discusses a proposed writing curriculum that would not unduly burden law schools or their faculty and concludes with additional, specific recommendations for incorporating writing across the curriculum—in doctrinal and writing courses—to improve students’ metacognitive skills and their ability to transfer those skills to practice

Canines in the Classroom: Service Animals in Primary and Secondary Educational Institutions

This Article focuses on the issue of whether a child with a disability has the legal right to attend a primary or secondary school with a service animal. It begins by setting forth basic information regarding the children who are currently receiving special education services and discussing the increasing number of animals placed into service with individuals under the age of eighteen, focusing on the recent trend of utilizing service animals to assist children with an autism spectrum disorder. Studies relating to the common argument against allowing service animals in schools – the impact of service animals on others with allergies to animal dander – are then examined. The Article continues with a brief summary of the federal law to provide a platform for analysis of the major cases in this area. As state laws that expand the rights of students appear to be an effective tool in litigation in this area, several of these laws are evaluated along with descriptions of language likely to be found in school district policies. State laws providing for trainers of service animals to have access to public accommodations, including schools, are then analyzed. The Article concludes by arguing that school districts need to be prepared with policies that provide for compliance with the law while still considering the impact of such animals on the school environment generally, given the legislative trends in this area

Takiff superalgebras and Conformal Field Theory

A class of non-semisimple extensions of Lie superalgebras is studied. They are obtained by adjoining to the superalgebra its adjoint representation as an abelian ideal. When the superalgebra is of affine Kac-Moody type, a generalisation of Sugawara's construction is shown to give rise to a copy of the Virasoro algebra and so, presumably, to a conformal field theory. Evidence for this is detailed for the extension of the affinisation of the superalgebra gl(1|1): Its highest weight irreducible modules are classified using spectral flow, the irreducible supercharacters are computed and a continuum version of the Verlinde formula is verified to give non-negative integer structure coefficients. Interpreting these coefficients as those of the Grothendieck ring of fusion, partial results on the true fusion ring and its indecomposable structures are deduced.Comment: 25 page
