The Comprehensive Archive of Substellar and Planetary Accretion Rates

S. K. Betti, K. B. Follette, K. Ward-Duong +11

Accretion rates () of young stars show a strong correlation with object mass (); however, extension of the relation into the substellar regime is less certa…

UV-Optical Emission of AB Aur b is Consistent with Scattered Stellar Light

Yifan Zhou, Brendan P. Bowler, Haifeng Yang +12

The proposed protoplanet AB Aur b is a spatially concentrated emission source imaged in the mm-wavelength disk gap of the Herbig Ae/Be star AB Aur. Its near-infrared spectrum and a…

An Introduction to High Contrast Differential Imaging of Exoplanets and Disks

Katherine B Follette

This tutorial is an introduction to High-Contrast Imaging, a technique that enables astronomers to isolate light from faint planets and/or circumstellar disks that would otherwise…

Correlating Changes in Spot Filling Factors with Stellar Rotation: The Case of LkCa 4

Facundo Pérez Paolino, Jeffrey S. Bary, Michael S. Petersen +4

We present a multi-epoch spectroscopic study of LkCa 4, a heavily spotted non-accreting T Tauri star. Using SpeX at NASA's Infrared Telescope Facility (IRTF), 12 spectra were colle…

Testing the Interaction Between a Substellar Companion and a Debris Disk in the HR 2562 System

Stella Yimiao Zhang, Gaspard Duchêne, Robert J. De Rosa +51

The HR 2562 system is a rare case where a brown dwarf companion resides in a cleared inner hole of a debris disk, offering invaluable opportunities to study the dynamical interacti…

Near-infrared Accretion Signatures from the Circumbinary Planetary Mass Companion Delorme 1 (AB)b

S. K. Betti, K. B. Follette, K. Ward-Duong +8

Accretion signatures from bound brown dwarf and protoplanetary companions provide evidence for ongoing planet formation, and accreting substellar objects have enabled new avenues t…
