A substellar flyby that shaped the orbits of the giant planets
Garett Brown, Renu Malhotra, Hanno Rein
The modestly eccentric and non-coplanar orbits of the giant planets pose a challenge to solar system formation theories which generally indicate that the giant planets emerged from…
Libration of Pluto's argument of perihelion and the role of the major planets
Takashi Ito, Renu Malhotra
Pluto's argument of perihelion is known to librate around . This libration is related to the secular phenomenon known as the von Zeipel-Lidov-Kozai (vZLK) oscillation. In…
The doubly librating Plutinos
Renu Malhotra, Takashi Ito
Named for orbital kinship with Pluto, the Plutinos are a prominent group of Kuiper Belt objects whose orbital periods are in libration about the 3/2 ratio with Neptune's. We invest…
Imaging of the Vega Debris System using JWST/MIRI
Kate Y. L. Su, Andras Gaspar, George H. Rieke +6
We present images of the Vega planetary debris disk obtained at 15.5, 23, and 25.5 microns with the Mid-Infrared Instrument (MIRI) on JWST. The debris system is remarkably symmetri…
