Kavli Affiliate: Avi Shporer | First 5 Authors: Canis Li, Avi Shporer, , , | Summary: We perform a systematic search for atmospheric variability in short-period gas-giant planets (hot Jupiters) observed by the Kepler mission, by looking for temporal variability of their secondary eclipse depths. This is motivated by a recent detection of a decrease […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Anirudh Chiti, Nora Shipp, Joshua D. Simon, Marla Geha | Summary: The Hercules ultra-faint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in identifying Hercules member stars. In […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Theodoros Papanikolaou, Xin-Chen He, Xiao-Han Ma, Yi-Fu Cai, Emmanuel N. Saridakis | Summary: We propose a new probe of primordial non-Gaussianities (NGs) through the observation of gravitational waves (GWs) induced by ultra-light ($M_{text{PBH}}< 10^{9}rm{g}$) primordial black holes (PBHs). Interestingly enough, the existence of primordial NG can leave […]

Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Feng Yuan, Zhiyuan Li, Zhao Su, Suoqing Ji | Summary: Supermassive black holes in galaxies spend majority of their lifetime in the low-luminosity regime, powered by hot accretion flow. Strong winds launched from the hot accretion flow have the potential to play an important role […]
Kavli Affiliate: Sara Seager | First 5 Authors: Nadiia M. Kostogryz, Alexander I. Shapiro, Veronika Witzke, Robert H. Cameron, Laurent Gizon | Summary: Stars appear darker at their limbs than at their disk centers because at the limb we are viewing the higher and cooler layers of stellar photospheres. Limb darkening derived from state-of-the-art stellar […]

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Michele L. Silverstein, Thomas Barclay, Joshua E. Schlieder, Karen A. Collins, Richard P. Schwarz | Summary: The nearby LHS 1678 (TOI-696) system contains two confirmed planets and a wide-orbit, likely-brown-dwarf companion, which orbit an M2 dwarf with a unique evolutionary history. The host star occupies a narrow […]
