What is Missing from the Local Stellar Halo?
Katherine Sharpe, Rohan P. Naidu, Charlie Conroy
The Milky Way's stellar halo, which extends to kpc, encodes the evolutionary history of our Galaxy. However, most studies of the halo to date have been limited to within a f…
Novae in M51: a New, Much Higher Rate from Multi-epoch HST Data
Shifra Mandel, Michael M. Shara, David Zurek +2
Accurate determination of the rates of nova eruptions in different kinds of galaxies give us strong constraints on those galaxies' underlying white dwarf and binary populations, an…
Dwarf galaxy archaeology from chemical abundances and star formation histories
James W. Johnson, Charlie Conroy, Benjamin D. Johnson +8
We model the stellar abundances and ages of two disrupted dwarf galaxies in the Milky Way stellar halo: Gaia-Sausage Enceladus (GSE) and Wukong/LMS-1. Using a statistically robust…
A trail of dark matter-free galaxies from a bullet dwarf collision
Pieter van Dokkum, Zili Shen, Michael A. Keim +8
The ultra-diffuse galaxies DF2 and DF4 in the NGC1052 group share several unusual properties: they both have large sizes, rich populations of overluminous and large globular cluste…
Live Fast, Die -Enhanced: The Mass-Metallicity- Relation of the Milky Way's Disrupted Dwarf Galaxies
Rohan P. Naidu, Charlie Conroy, Ana Bonaca +9
The Milky Way's satellite galaxies ("surviving dwarfs") have been studied for decades as unique probes of chemical evolution in the low-mass regime. Here we extend such studies to…
Unicorns and Giraffes in the binary zoo: stripped giants with subgiant companions
Kareem El-Badry, Rhys Seeburger, Tharindu Jayasinghe +5
We analyze two binary systems containing giant stars, V723 Mon ("the Unicorn") and 2M04123153+6738486 ("the Giraffe"). Both giants orbit more massive but less luminous companions,…
