Mapping Active Star-Formation in Serpens and the Aquila Rift

T. A. Rector, R. M. P. Kerr, L. Prato +4

We report the results of a high-sensitivity survey for Herbig-Haro (HH) outflows in the Serpens-Aquila Rift using the DECam instrument on the 4-meter telescope. We have detected 88…

SPYGLASS. VII-B. Tracing the Fragments of Massive Star Formation Using Low-Mass Associations

Ronan Kerr, Adam L. Kraus, Jonathan C. Tan +6

New observations from the Gaia spacecraft have traced an emerging demographic of low-mass associations disconnected from larger associations or GMCs. The first of these association…

TESS Hunt for Young and Maturing Exoplanets (THYME) XIV: A Comoving-Based Age Constraint for KELT-20

Adam Distler, Melinda Soares-Furtado, Andrew W. Mann +9

Young stellar moving groups offer unique opportunities to investigate the early evolution of stellar and planetary systems. In continuation of an ongoing effort to age-date compell…

SPYGLASS. VII-A. The Demographics and Ages of Small Nearby Young Associations

Ronan Kerr, Facundo Peŕez Paolino, Jonathan C. Tan +5

Recent Gaia-based young stellar association surveys have revealed dozens of low-mass populations that have, until recently, been too small or sparse to detect. These populations re…

THYME XIII: Two young Neptunes orbiting a 75-Myr star in the Alpha Persei Cluster

Anne Dattilo, Andrew M. Vanderburg, Madyson G. Barber +28

Young planets with mass measurements are particularly valuable in studying atmospheric mass-loss processes, but these planets are rare and their masses difficult to measure due to…

The JCMT Gould Belt Survey Complete Core Catalogue: Core mass function variations between nearby molecular clouds

Kate Pattle, James Di Francesco, Jenny Hatchell +14

We present a catalogue of dense cores identified in James Clerk Maxwell Telescope (JCMT) Gould Belt Survey SCUBA-2 observations of nearby star-forming clouds. We identified 2257 de…
