Absolute dimensions of the unevolved F-type eclipsing binary BT Vulpeculae

Guillermo Torres, Claud H. Sandberg Lacy, Francis C. Fekel +1

We report extensive differential V-band photometry and high-resolution spectroscopy for the 1.14 day, detached, double-lined eclipsing binary BT Vul (F0+F7). Our radial-velocity mo…

The quadruple-lined, doubly-eclipsing system V482 Persei

Guillermo Torres, Claud H. Sandberg Lacy, Francis C. Fekel +2

We report spectroscopic and differential photometric observations of the A-type system V482 Per that reveal it to be a rare hierarchical quadruple system containing two eclipsing b…

On the nature of quiescent light curves demonstrated by WZ Sge stars

D. A. Kononov, C. H. S. Lacy, V. B. Puzin +3

We present the results of simultaneous spectroscopic and photometric observations of the cataclysmic variable star (hereafter CVs) V455 Andromedae, belonging to the WZ Sge sub-clas…

Precise mass and radius measurements for the components of the bright solar-type eclipsing binary star V1094 Tau

P. F. L. Maxted, R. J. Hutcheon, G. Torres +6

V1094 Tau is bright eclipsing binary star with an orbital period close to 9 days containing two stars similar to the Sun. Our aim is to test models of Sun-like stars using precise…

The Benchmark Eclipsing Binary V530 Ori: A Critical Test of Magnetic Evolution Models for Low-Mass Stars

Guillermo Torres, Claud H. Sandberg Lacy, Kresimir Pavlovski +4

We report accurate measurements of the physical properties (mass, radius, temperature) of components of the G+M eclipsing binary V530 Ori. The M-type secondary shows a larger radiu…

The Black Hole Mass Function Derived from Local Spiral Galaxies

Benjamin L. Davis, Joel C. Berrier, Lucas Johns +6

We present our determination of the nuclear supermassive black hole (SMBH) mass function for spiral galaxies in the Local Universe, established from a volume-limited sample consist…
