Temporal Evolution of the Size and Temperature of Betelgeuse's Extended Atmosphere
Eamon O'Gorman, Graham M. Harper, Alexander Brown +4
We use the Very Large Array (VLA) in the A configuration with the Pie Town (PT) Very Long Baseline Array (VLBA) antenna to spatially resolve the extended atmosphere of Betelgeuse o…
The White Dwarfs within 25 Parsecs of the Sun: Kinematics and Spectroscopic Subtypes
E. M. Sion, J. B. Holberg, T. D. Oswalt +3
We present the fractional distribution of spectroscopic subtypes, range and distribution of surface temperatures, and kinematical properties of the white dwarfs within 25pc of the…
The Age and The Mass of The αHerculis Triple-Star System From A MESA Grid of rotating stars with 1.3 <= M/Msun <= 8.0
Ehsan Moravveji, Edward F. Guinan, Habib G. Khosroshahi +1
α^1 Her is the second closest Asymptotic Giant Branch (AGB) star to the Sun, and the variable luminous M5 Ib-II member of a triple stellar system containing G8 III and A9 IV-V comp…
The period change of the Cepheid Polaris suggests enhanced mass loss
Hilding R. Neilson, Scott G. Engle, Ed Guinan +3
Polaris is one of the most observed stars in the night sky, with recorded observations spanning more than 200 years. From these observations, one can study the real-time evolution…
The White Dwarfs within 20 Parsecs of the Sun: Kinematics and Statistics
Edward M. Sion, Jay B. Holberg, Terry D. Oswalt +2
We present the kinematical properties, distribution of spectroscopic subtypes, stellar population subcomponents of the white dwarfs within 20 pc of the sun. We find no convincing e…
