An observational upper limit on the rate of gamma-ray bursts with neutron star-black hole merger progenitors

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Eric Burns, Philippe Landry, Salvatore Vitale, | Summary: Compact-object binary mergers consisting of one neutron star and one black hole (NSBHs) have long been considered promising progenitors for gamma-ray bursts, whose central engine remains poorly understood. Using gravitational-wave constraints on the population-level NSBH mass and […]

A Transiting Super-Earth in the Radius Valley and An Outer Planet Candidate Around HD 307842

Kavli Affiliate: Avi Shporer | First 5 Authors: Xinyan Hua, Sharon Xuesong Wang, Johanna K. Teske, Tianjun Gan, Avi Shporer | Summary: We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial velocity (RV) measurements constrain the […]

A calibration point for stellar evolution from massive star asteroseismology

Kavli Affiliate: George Ricker | First 5 Authors: Siemen Burssens, Dominic M. Bowman, Mathias Michielsen, Sergio Simón-Díaz, Conny Aerts | Summary: Massive stars are progenitors of supernovae, neutron stars and black holes. During the hydrogen-core burning phase their convective cores are the prime drivers of their evolution, but inferences of core masses are subject to […]
