TESS Hunt for Young and Maturing Exoplanets (THYME) X: a two-planet system in the 210 Myr MELANGE-5 Association

Kavli Affiliate: George R. Ricker | First 5 Authors: Pa Chia Thao, Andrew W. Mann, Madyson G. Barber, Adam L. Kraus, Benjamin M. Tofflemire | Summary: Young (<500 Myr) planets are critical to studying how planets form and evolve. Among these young planetary systems, multi-planet configurations are particularly useful as they provide a means to […]

Electric leakage suppression of phase-transforming ferroelectrics with donor impurities

Kavli Affiliate: Xian Chen | First 5 Authors: Chenbo Zhang, Xiaotong Peng, Bo Liu, Kai Zhang, Xian Chen | Summary: Phase-transforming ferroelectric materials are widely used in energy harvesting and conversion devices. However, the functionality of these devices is significantly impeded by electrical leakage at high temperatures. In this study, we fundamentally study the mechanism […]

Measurements of the branching fractions of $Ξ_{c}^{0}toΞ^{0}π^{0}$, $Ξ_{c}^{0}toΞ^{0}η$, and $Ξ_{c}^{0}toΞ^{0}η^{prime}$ and asymmetry parameter of $Ξ_{c}^{0}toΞ^{0}π^{0}$

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We present a study of $Xi_{c}^{0}toXi^{0}pi^{0}$, $Xi_{c}^{0}toXi^{0}eta$, and $Xi_{c}^{0}toXi^{0}eta^{prime}$ decays using the Belle and Belle~II data samples, which have integrated luminosities of 980~$mathrm{fb}^{-1}$ and 426~$mathrm{fb}^{-1}$, respectively. We measure the following relative branching fractions $${cal B}(Xi_{c}^{0}toXi^{0}pi^{0})/{cal B}(Xi_{c}^{0}toXi^{-}pi^{+}) […]
