Direct-imaging Discovery of a Substellar Companion Orbiting the Accelerating Variable Star HIP 39017

The Astronomical Journal
We present the direct-imaging discovery of a substellar companion (a massive planet or low-mass brown dwarf) to the young, γ Doradus ( γ Dor)-type variable star HIP 39017 (HD 65526). The companion’s SCExAO/CHARIS JHK (1.1–2.4 μ m) spectrum and Keck/NIRC2

Asteroid Mass Estimation by Mutual Perturbations During Close Encounters After Gaia Focused Product Release

The Astronomical Journal
Mutual perturbations between asteroids during close encounters allow the estimation of their masses using precise astrometric observations. We use all astrometry reported to the Minor Planet Center, high-precision astrometry from ESA’s Gaia Focused ...
