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 […]

Outshining by Recent Star Formation Prevents the Accurate Measurement of High-z Galaxy Stellar Masses

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Desika Narayanan, Sidney Lower, Paul Torrey, Gabriel Brammer, Weiguang Cui | Summary: In this paper, we demonstrate that the inference of galaxy stellar masses via spectral energy distribution (SED) fitting techniques for galaxies formed in the first billion years after the Big Bang carries fundamental uncertainties owing […]
