COSMIC Variance in Binary Population Synthesis
Katelyn Breivik, Scott Coughlin, Michael Zevin +8
The formation and evolution of binary stars is a critical component of several fields in astronomy. The most numerous sources for gravitational wave observatories are inspiraling a…
LISA and the Existence of a Fast-Merging Double Neutron Star Formation Channel
Jeff J. Andrews, Katelyn Breivik, Chris Pankow +2
Using a Milky Way double neutron star (DNS) merger rate of 210 Myr, as derived by the Laser Interferometer Gravitational-Wave Observatory (LIGO), we demonstrate that the Las…
Weighing the Darkness: Astrometric Mass Measurement of Hidden Stellar Companions using Gaia
Jeff J. Andrews, Katelyn Breivik, Sourav Chatterjee
In astrometric binaries, the presence of a dark, unseen star can be inferred from the gravitational pull it induces on its luminous binary companion. While the orbit of such binari…
The Complete Evolution of a Neutron-Star Binary through a Common Envelope Phase Using 1D Hydrodynamic Simulations
Tassos Fragos, Jeff J. Andrews, Enrico Ramirez-Ruiz +4
Over forty years of research suggests that the common envelope phase, in which an evolved star engulfs its companion upon expansion, is the critical evolutionary stage forming shor…
Voyage 2050 White Paper: All-Sky Visible and Near Infrared Space Astrometry
David Hobbs, Anthony Brown, Erik Høg +27
A new all-sky visible and Near-InfraRed (NIR) space astrometry mission with a wavelength cutoff in the K-band is not just focused on a single or small number of key science cases.…
Did GW170817 harbor a pulsar?
Enrico Ramirez-Ruiz, Jeff J. Andrews, Sophie L. Schrøder
If the progenitor of GW170817 harbored a pulsar, then a Poynting flux dominated bow-shock cavity would have been expected to form around the traveling binary. The characteristic si…
Double Neutron Star Formation: Merger Times, Systemic Velocities, and Travel Distances
Jeff J. Andrews, Andreas Zezas
The formation and evolution of double neutron stars (DNS) have traditionally been studied using binary population synthesis. In this work, we take an alternative approach by focusi…
Double Neutron Star Populations and Formation Channels
Jeff J. Andrews, Ilya Mandel
In the past five years, the number of known double neutron stars (DNS) in the Milky Way has roughly doubled. We argue that the observed sample can be split into three distinct sub-…
