Probing Projection Effects in Optically-Selected Clusters with Velocity Dispersions Outliers
K. Graham, T. E. Jeltema, C. -H. To +8
The evolution of galaxy cluster abundance is a powerful probe of cosmology, but its efficacy depends on our ability to understand and control for systematics in the selection and m…
Cool Cores in Clusters of Galaxies in the Dark Energy Survey
K. Graham, J. O'Donnell, M. M. Silverstein +54
We search for the presence of cool cores in optically-selected galaxy clusters from the Dark Energy Survey (DES) and investigate their prevalence as a function of redshift and clus…
Outbursts and stellar properties of the classical Be star HD 6226
Noel D. Richardson, Olivier Thizy, Jon E. Bjorkman +58
The bright and understudied classical Be star HD 6226 has exhibited multiple outbursts in the last several years during which the star grew a viscous decretion disk. We analyze 659…
Evolution of the disk of pi Aqr: from near-disappearance to a strong maximum
Y. Naze, G. Rauw, J . Guarro Flo +30
Some Be stars display important variability of the strength of the emission lines formed in their disk. This is notably the case of pi Aqr. We present here the recent evolution of…
The Rise and Fall of the King: The Correlation between FO Aquarii's Low States and the White Dwarf's Spindown
Colin Littlefield, Peter Garnavich, Mark R. Kennedy +45
The intermediate polar FO Aquarii (FO Aqr) experienced its first-reported low-accretion states in 2016, 2017, and 2018, and using newly available photographic plates, we identify p…
The KIC 8462852 Light Curve From 2015.75 to 2018.18 Shows a Variable Secular Decline
Bradley E. Schaefer, Rory O. Bentley, Tabetha S. Boyajian +19
The star KIC 8462852 (Boyajian's Star) displays both fast dips of up to 20% on time scales of days, plus long-term secular fading by up to 19% on time scales from a year to a centu…
