Blanco DECam Bulge Survey (BDBS) III: A new view of the double red clump in the Milky Way bulge through luminosity and color distribution
Dongwook Lim, Andreas J. Koch-Hansen, Chul Chung +9
Red clump (RC) stars are one of the best stellar tracers of the structure of the Milky Way (MW) bulge. Here we report a new view of the double RC through luminosity and color distr…
Migration of Gas Giant Planets in Gravitationally Unstable Disks
Scott Michael, Richard H. Durisen, Aaron C. Boley
Characterization of migration in gravitationally unstable disks is necessary to understand the fate of protoplanets formed by disk instability. As part of a larger study, we are us…
A 3D Hydrodynamics Study of Gravitational Instabilities in a Young Circumbinary Disc
Karna M. Desai, Thomas Y. Steiman-Cameron, Scott Michael +2
We present a 3D hydrodynamics study of gravitational instabilities (GIs) in a 0.14 M circumbinary protoplanetary disc orbiting a 1 M star and a 0.02 M…
Blanco DECam Bulge Survey (BDBS) IV: Metallicity Distributions and Bulge Structure from 2.6 Million Red Clump Stars
Christian I. Johnson, R. Michael Rich, Iulia T. Simion +12
We present photometric metallicity measurements for a sample of 2.6 million bulge red clump stars extracted from the Blanco DECam Bulge Survey (BDBS). Similar to previous studies,…
The Blanco DECam Bulge Survey. I. The Survey Description and Early Results
R. Michael Rich, Christian I. Johnson, Michael Young +18
The Blanco Dark Energy Camera (DECam) Bulge survey is a Vera Rubin Observatory (LSST) pathfinder imaging survey, spanning sq. deg. of the Southern Galactic bulge, $-2^\c…
The Effects of Metallicity and Grain Size on Gravitational Instabilities in Protoplanetary Disks
Kai Cai, Richard H. Durisen, Scott Michael +4
Observational studies show that the probability of finding gas giant planets around a star increases with the star's metallicity. Our latest simulations of disks undergoing gravita…
