Orbital Period Changes in WZ Sagittae
Joseph Patterson, Geoffrey Stone, Jonathan Kemp +19
We report a long-term (1961-2017) study of the eclipse times in the dwarf nova WZ Sagittae, in an effort to learn its rate of orbital-period change. Some wiggles with a time scale…
A Bright Short Period M-M Eclipsing Binary from the KELT Survey: Magnetic Activity and the Mass-Radius Relationship for M-dwarfs
Jack B. Lubin, Joseph E. Rodriguez, George Zhou +26
We report the discovery of KELT J041621-620046, a moderately bright (J10.2) M dwarf eclipsing binary system at a distance of 393 pc. KELT J041621-620046 was first identi…
WASP-167b/KELT-13b: Joint discovery of a hot Jupiter transiting a rapidly-rotating F1V star
L. Y. Temple, C. Hellier, M. D. Albrow +46
We report the joint WASP/KELT discovery of WASP-167b/KELT-13b, a transiting hot Jupiter with a 2.02-d orbit around a = 10.5, F1V star with [Fe/H] = 0.1 0.1. The 1.5 R$_{\…
Effective Temperatures of Cataclysmic Variable White Dwarfs as a Probe of their Evolution
A. F. Pala, B. T. Gänsicke, D. Townsley +29
We present HST spectroscopy for 45 cataclysmic variables (CVs), observed with HST/COS and HST/STIS. For 36 CVs, the white dwarf is recognisable through its broad Ly absorption p…
Resynchronization of the Asynchronous Polar CD Ind
G. Myers, J. Patterson, E. de Miguel +6
CD Ind is one of only four confirmed asynchronous polars (APs). APs are strongly magnetic cataclysmic variables of the AM Herculis subclass with the characteristic that their white…
