Kavli Affiliate: Avi Shporer | First 5 Authors: Mohammed El Mufti, Peter P. Plavchan, Howard Isaacson, Bryson L. Cale, Dax L. Feliz | Summary: We validate the presence of a two-planet system orbiting the 0.2–1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system consists of an inner moderately eccentric transiting mini-Neptune (TOI 560 b, […]

Kavli Affiliate: Subo Dong | First 5 Authors: Ping Chen, Subo Dong, Chris Ashall, S. Benetti, D. Bersier | Summary: Using data from the Complete Nearby ($z_{host}<0.02$) sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the $B-V$ color curves of Type Ia supernovae: the "color stretch" $s_{BV}$ […]
