Absolute dimensions of the F-type eclipsing binary star VZ Cephei
Guillermo Torres, Claud H. Sandberg Lacy
We present new V-band differential photometry and radial-velocity measurements of the unevolved 1.18-day period F+G-type double-lined eclipsing binary VZ Cep. We determine accurate…
Absolute properties of the spotted eclipsing binary star CV Bootis
Guillermo Torres, Luiz Paulo R. Vaz, Claud H. Sandberg Lacy
We present new V-band differential brightness measurements as well as new radial-velocity measurements of the detached, circular, 0.84-day period, double-lined eclipsing binary sys…
Discovery of a relationship between spiral arm morphology and supermassive black hole mass in disk galaxies
Marc S. Seigar, Daniel Kennefick, Julia Kennefick +1
We present a relationship between spiral arm pitch angle (a measure of the tightness of spiral structure) and the mass of supermassive black holes (BHs) in the nuclei of disk galax…
