Distant TNO Inclinations as a Constraint on Primordial Cluster Perturbations in the Presence of Planet Nine

Avni Bansal, Ian Brunton, Konstantin Batygin +2

The Sun was almost certainly born in a stellar cluster, implying some degree of external forcing from neighboring stars during the Solar System's infancy. Published estimates of th…

Detection of propadiene (CHCCH), propene (CH) and non-detection of propane (CH) in Jupiter's northern polar stratosphere

James A. Sinclair, Thomas K. Greathouse, Rohini S. Giles +8

We report the first detection of stratospheric propadiene (CHCCH) and propene (CH) at Jupiter's mid-to-high northern latitudes using IRTF-TEXES measurements recorde…

The compositions of the HR 8799 planets reflect accretion of both solids and metal-enriched gas

Jerry W. Xuan, Jean-Baptiste Ruffio, Yayaati Chachan +24

With four giant planets (, $T_\rm{eff}\sim900-1200$ K) orbiting between 15-70 au, HR 8799 provides an unparalleled testbed for studying giant planet formatio…
