Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Razieh Emami, Lars Hernquist, Randall Smith, James F. Steiner, Grant Tremblay | Summary: We undertake a comprehensive investigation into the distribution of in~situ stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with data from the H3 survey. Our analysis reveals that 28% of […]

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Devarshi Choudhury, Tuomo Salmi, Serena Vinciguerra, Thomas E. Riley, Yves Kini | Summary: We report Bayesian inference of the mass, radius and hot X-ray emitting region properties – using data from the Neutron Star Interior Composition ExploreR (NICER) – for the brightest rotation-powered millisecond X-ray pulsar […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Madyson G. Barber, Pa Chia Thao, Andrew W. Mann, Andrew Vanderburg, Mayuko Mori | Summary: The youngest ($<$50 Myr) planets are vital to understand planet formation and early evolution. The 17 Myr system HIP 67522 is already known to host a giant ($simeq$10$R_oplus$) planet on a tight […]

Kavli Affiliate: George R. Ricker | First 5 Authors: Emma Nabbie, Chelsea X. Huang, Jennifer A. Burt, David J. Armstrong, Eric E. Mamajek | Summary: The recent discoveries of Neptune-sized ultra-short period planets (USPs) challenge existing planet formation theories. It is unclear whether these residents of the Hot Neptune Desert have similar origins to smaller, […]
