An excess of luminous white dwarfs in the peculiar Galactic globular cluster NGC 2808
Laksh Gupta, Samyaday Choudhury, Annalisa Calamida +2
We study the white dwarf (WD) cooling sequence of the Galactic Globular Cluster (GGC) NGC 2808 by using deep near-UV data from the Hubble Space Telescope and theoretical models, to…
SKYSURF-11: A New Zodiacal Light Model Optimized for Optical Wavelengths
Rosalia O'Brien, Richard G. Arendt, Rogier A. Windhorst +15
We present an improved zodiacal light model, optimized for optical wavelengths, using archival Hubble Space Telescope (HST) imaging from the SKYSURF program. The Kelsall et al. 199…
Betelgeuse's Buddy: X-Ray Constraints on the Nature of Ori B
Anna J. G. O'Grady, Brendan O'Connor, Jared A. Goldberg +8
The d Long Secondary Period of Betelgeuse's optical lightcurve and radial velocity motivated the prediction of a low-mass stellar companion, expected to be at maximal a…
Betelgeuse, Betelgeuse, Betelgeuse, Betel-buddy? Constraints on the dynamical companion to Orionis from HST
Jared A. Goldberg, Anna J. G. O'Grady, Meridith Joyce +10
Recently, two independent analyses have asserted that the cause of the Long Secondary Period (LSP) observed in the variability spectrum of our nearest red supergiant, Betelgeuse ($…
