Characterization of K2-167 b and CALM, a new stellar activity mitigation method

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Zoë L. de Beurs, Andrew Vanderburg, Erica Thygesen, Joseph E. Rodriguez, Xavier Dumusque | Summary: We report precise radial velocity (RV) observations of HD 212657 (= K2-167), a star shown by K2 to host a transiting sub-Neptune-sized planet in a 10 day orbit. Using Transiting Exoplanet Survey […]

Study of $Υ(10753)$ decays to $π^{+}π^{-}Υ(nS)$ final states at Belle II

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We present an analysis of the process $e^{+}e^{-}topi^{+}pi^{-}Upsilon(nS)$ (where $n$ = 1, 2, or 3) reconstructed in $19.6rm$ $rm fb^{-1}$ of Belle II data during a special run of the SuperKEKB collider at four […]

Hot Jupiter Formation in Dense Star Clusters

Posted by dbos Peking

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Leonard Benkendorff, Francesco Flammini Dotti, Katja Stock, Maxwell Xu Cai, Rainer Spurzem | Summary: Hot Jupiters (HJ) are defined as Jupiter-mass exoplanets orbiting around their host star with an orbital period < 10 days. It is assumed that HJ do not form in-situ but ex-situ. Recent discoveries […]
