Mergers of black hole-neutron star (BHNS) binaries have now been observed by GW detectors with the recent announcement of GW200105 and GW200115. Such observations not only provide…
Wind mass-loss rates of stripped stars inferred from Cygnus X-1
Coenraad J. Neijssel, Serena Vinciguerra, Alejandro Vigna-Gomez +5
Recent observations of the high-mass X-ray binary Cygnus X-1 have shown that both the companion star (41 solar masses) and the black hole (21 solar masses) are more massive than pr…
Cygnus X-1 contains a 21-solar mass black hole -- implications for massive star winds
James C. A. Miller-Jones, Arash Bahramian, Jerome A. Orosz +23
The evolution of massive stars is influenced by the mass lost to stellar winds over their lifetimes. These winds limit the masses of the stellar remnants (such as black holes) that…
Chemically Homogeneous Evolution: A rapid population synthesis approach
Jeff Riley, Ilya Mandel, Pablo Marchant +5
We explore chemically homogeneous evolution (CHE) as a formation channel for massive merging binary black holes (BBHs). We develop methods to include CHE in a rapid binary populati…
Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network
K. Ackley, V. B. Adya, P. Agrawal +160
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influen…
Be X-ray binaries in the SMC as indicators of mass transfer efficiency
Serena Vinciguerra, Coenraad J. Neijssel, Alejandro Vigna-Gómez +7
Be X-ray binaries (BeXRBs) consist of rapidly rotating Be stars with neutron star companions accreting from the circumstellar emission disk. We compare the observed population of B…
Luminous Red Novae: population models and future prospects
George Howitt, Simon Stevenson, Alejandro Vigna-Gómez +5
A class of optical transients known as Luminous Red Novae (LRNe) have recently been associated with mass ejections from binary stars undergoing common-envelope evolution. We use th…
Common-Envelope Episodes that lead to Double Neutron Star formation
Alejandro Vigna-Gómez, Morgan MacLeod, Coenraad J. Neijssel +6
Close double neutron stars have been observed as Galactic radio pulsars, while their mergers have been detected as gamma-ray bursts and gravitational-wave sources. They are believe…
Detecting Double Neutron Stars with LISA
Mike Y. M. Lau, Ilya Mandel, Alejandro Vigna-Gómez +3
We estimate the properties of the double neutron star (DNS) population that will be observable by the planned space-based interferometer LISA. By following the gravitational radiat…
