A Framework for Linking Pre- and Post-Common Envelope Binary Properties with Star Clusters: The First Demonstration with a Massive White Dwarf+M Dwarf Binary in Alessi 12
Steffani M. Grondin, Maria R. Drout, Jason Nordhaus +12
Common envelope (CE) evolution is a critical phase in the lives of binary stars, producing close binaries that are progenitors of type Ia supernovae and gravitational wave sources.…
Stellar Multiplicity of M Dwarfs with Short-period Giant Planets, and the Characterization of TOI-5628Ab
Tianjun Gan, Alexandrine L'Heureux, Charles Cadieux +33
Binary stars are ubiquitous, yet it remains unclear how wide-orbit stellar companions influence the formation of hot Jupiters, particularly around M dwarfs. Here, we first report t…
How Common Are Common Envelopes? Quantifying Their Role in Forming Gravitational-Wave Sources
Floor S. Broekgaarden, Ana Lam, Sasha Levina +14
A central goal of gravitational-wave astronomy is to use merging binary black hole (BBH), black hole-neutron star (BHNS), and binary neutron star (BNS) systems as fossils to recons…
The ejection and detectability of high- and hyper-velocity stars by compact object binaries in globular clusters
Fraser A. Evans, Steffani M. Grondin, Claire S. Ye +3
The dense cores of Milky Way globular clusters (GCs) play host to a variety of dynamical encounters between stellar objects, which can accelerate stars to velocities high enough to…
A systematic method to identify runaways from star clusters produced from single-binary interactions: A case study of M67
A. Herrera-Urquieta, N. Leigh, J. Pinto +9
One hypothesis for runaway stars (RSs) is that they are ejected from star clusters with high velocities relative to the cluster center-of-mass motion. There are two competing mecha…
The first catalog of candidate white dwarf-main sequence binaries in open star clusters: A new window into common envelope evolution
Steffani M. Grondin, Maria R. Drout, Jason Nordhaus +3
Close binary systems are the progenitors to both Type Ia supernovae and the compact object mergers that can be detected via gravitational waves. To achieve a binary with a small ra…
A catalogue of Galactic GEMS: Globular cluster Extra-tidal Mock Stars
Steffani M. Grondin, Jeremy J. Webb, James M. M. Lane +2
This work presents the Globular cluster Extra-tidal Mock Star (GEMS) catalogue of extra-tidal stars and binaries created via three-body dynamical encounters in globular cluster cor…
The dominant mechanism(s) for populating the outskirts of star clusters with neutron star binaries
Nathan W. C. Leigh, Claire S. Ye, Steffani M. Grondin +3
It has been argued that heavy binaries composed of neutron stars (NSs) and millisecond pulsars (MSPs) can end up in the outskirts of star clusters via an interaction with a massive…
Searching for the extra-tidal stars of globular clusters using high-dimensional analysis and a core particle spray code
Steffani M. Grondin, Jeremy J. Webb, Nathan W. C. Leigh +2
Three-body interactions can eject stars from the core of a globular cluster, causing them to enter the Galactic halo as extra-tidal stars. While finding extra-tidal stars is impera…
Strong-field Gravity Tests with the Double Pulsar
M. Kramer, I. H. Stairs, R. N. Manchester +27
Continued observations of the Double Pulsar, PSR J0737-3039A/B, consisting of two radio pulsars (A and B) that orbit each other with a period of 2.45hr in a mildly eccentric (e=0.0…
Massive White Dwarfs in Young Star Clusters
Harvey B. Richer, Ilaria Caiazzo, Helen Du +6
We have carried out a search for massive white dwarfs (WDs) in the direction of young open star clusters using the Gaia DR2 database. The aim of this survey was to provide robust d…
