Using APOGEE Wide Binaries to Test Chemical Tagging with Dwarf Stars
Jeff J. Andrews, Borja Anguiano, Julio Chanamé +4
Stars of a common origin are thought to have similar, if not nearly identical, chemistry. Chemical tagging seeks to exploit this fact to identify Milky Way subpopulations through t…
Constraining Compact Object Formation with 2M0521
Katelyn Breivik, Sourav Chatterjee, Jeff J. Andrews
We show that the recently discovered binary 2M05215658+4359220 (2M0521), comprised of a giant star (GS) orbiting a suspected black hole (BH) in a ~80 day orbit, may be instrumental…
r-process enrichment of ultra-faint dwarf galaxies by fast merging double neutron stars
Mohammadtaher Safarzadeh, Enrico Ramirez-Ruiz, Jeff. J. Andrews +3
The recent aLIGO/aVirgo discovery of gravitational waves from the neutron star merger (NSM) GW170817 and the follow up kilonova observations have shown that NSMs produce copious am…
A Serendipitous Pulsar Discovery in a Search for a Companion to a Low-Mass White Dwarf
Jeff J. Andrews, Marcel A. Agüeros, Fernando Camilo +4
We report the discovery of a previously unidentified pulsar as part of a radio campaign to identify neutron star companions to low-mass white dwarfs (LMWDs) using the Robert C.\ By…
Validating TGAS wide binaries with Gaia DR2 Radial Velocities and Parallaxes
Jeff J. Andrews, Julio Chanamé, Marcel A. Agüeros
Featuring greatly improved astrometry and precise radial velocities (RVs), the second data release (DR2) from Gaia affords us a unique opportunity to test the validity of samples o…
The spin of the second-born black hole in coalescing binary black holes
Y. Qin, T. Fragos, G. Meynet +3
Various binary black hole formation channels have been proposed since the first gravitational event GW150914 was discovered by the Advanced Laser Interferometer Gravitational-Wave…
