LAMOST J0140355+392651: An evolved cataclysmic variable donor transitioning to become an extremely low mass white dwarf
Kareem El-Badry, Eliot Quataert, Hans-Walter Rix +6
We present LAMOST J0140355+392651 (hereafter J0140), a close ( hours) binary containing a bloated, low-mass () proto-white dwarf (WD)…
Neutral CGM as damped Lyα absorbers at high redshift
Jonathan Stern, Amiel Sternberg, Claude-André Faucher-Giguère +8
Recent searches for the hosts of high-redshift () damped Ly absorbers (DLAs) have detected bright galaxies at distances of tens of kpc from the DLA. Using the FIRE-2 c…
A million binaries from Gaia eDR3: sample selection and validation of Gaia parallax uncertainties
Kareem El-Badry, Hans-Walter Rix, Tyler M. Heintz
We construct from Gaia eDR3 an extensive catalog of spatially resolved binary stars within 1 kpc of the Sun, with projected separations ranging from a few au to 1 pc. We…
The origin of metal-poor stars on prograde disk orbits in FIRE simulations of Milky Way-mass galaxies
Isaiah B. Santistevan, Andrew Wetzel, Robyn E. Sanderson +3
In hierarchical structure formation, metal-poor stars in and around the Milky Way (MW) originate primarily from mergers of lower-mass galaxies. A common expectation is therefore th…
TOI-1259Ab -- a gas giant planet with 2.7% deep transits and a bound white dwarf companion
David V. Martin, Kareem El-Badry, Vedad Kunovac Hodžić +33
We present TOI-1259Ab, a 1.0 Rjup gas giant planet transiting a 0.71 Rsun K-dwarf on a 3.48 day orbit. The system also contains a bound white dwarf companion TOI-1259B with a proje…
Probing the CGM of Low-redshift Dwarf Galaxies Using FIRE Simulations
Fei Li, Mubdi Rahman, Norman Murray +7
Observations of UV metal absorption lines have provided insight into the structure and composition of the circumgalactic medium (CGM) around galaxies. We compare these observations…
