Finding the Instability Strip for Accreting Pulsating White Dwarfs from HST and Optical Observations

Paula Szkody, Anjum Mukadam, Boris T. Gansicke +9

Time-resolved low resolution Hubble Space Telescope ultraviolet spectra together with ground-based optical photometry and spectra are used to constrain the temperatures and pulsati…

A wide-field HI mosaic of Messier 31. II.The disk warp, rotation and the dark matter halo

Edvige Corbelli, Silvio Lorenzoni, René A. M. Walterbos +2

We test cosmological models of structure formation using the rotation curve of the nearest spiral galaxy, M31, determined using a recent deep, full-disk 21-cm imaging survey smooth…

A multi-wavelength study of the young star V1118 Orionis in outburst

M. Audard, G. S. Stringfellow, M. Güdel +6

Abriged version for astroph: The young late-type star V1118 Orionis was in outburst from 2005 to 2006. We followed the outburst with optical and near-infrared photometry; the X-ray…

Halo Gas and Galaxy Disk Kinematics Derived from Observations and LCDM Simulations of MgII Absorption Selected Galaxies at Intermediate Redshift

G. G. Kacprzak, C. W. Churchill, D. Ceverino +3

We obtained ESI/Keck rotation curves of 10 MgII absorption selected galaxies (0.3 < z < 1.0) for which we have WFPC-2/HST images and high resolution HIRES/Keck and UVES/VLT quasar…

Modeling the Subsurface Structure of Sunspots

H. Moradi, C. Baldner, A. C. Birch +19

While sunspots are easily observed at the solar surface, determining their subsurface structure is not trivial. There are two main hypotheses for the subsurface structure of sunspo…

Day-side z'-band emission and eccentricity of Wasp-12b

Mercedes Lopez-Morales, Jeffrey L. Coughlin, David K. Sing +5

We report the detection of the eclipse of the very-hot Jupiter WASP-12b via z'-band time-series photometry obtained with the 3.5-meter ARC telescope at Apache Point Observatory. We…
