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…
Stellar populations in STARFORGE II: Comparison with observations
Juan P. Farias, Stella S. R. Offner, Ronan Kerr +1
Recent studies suggest that most star-forming regions in our Galaxy form stellar associations rather than bound clusters. We analyse models from the STARFORGE simulation suite, a s…
The Herbig-Haro Outflow Content and Star-Forming Environment of Circinus West and East
T. A. Rector, L. Prato, R. Kerr +2
We report the results of a spatially compete, high-sensitivity survey for Herbig-Haro (HH) outflows in the Western and Eastern Circinus molecular clouds. We have detected 28 new HH…
SPYGLASS. VI. Feedback-Driven Star Formation in the Circinus Complex
Ronan Kerr, Juan P. Farias, Lisa Prato +3
Young associations provide a record that traces the star formation process, and the youngest populations connect progenitor gas dynamics to the resulting stellar populations. We th…
TESS Hunt for Young and Maturing Exoplanets (THYME) XII: A Young Mini-Neptune on the Upper Edge of the Radius Valley in the Hyades Cluster
Adam Distler, Melinda Soares-Furtado, Andrew Vanderburg +18
We present the discovery and characterization of TOI-4364\,b, a young mini-Neptune in the tidal tails of the Hyades cluster, identified through TESS transit observations and ground…
The Scuti stars of the Cep--Her Complex. I: Pulsator fraction, rotation, asteroseismic large spacings, and the relation
Simon J. Murphy, Timothy R. Bedding, Anuj Gautam +2
We identify delta Scuti pulsators amongst members of the recently-discovered Cep--Her Complex using light curves from the Transiting Exoplanet Survey Satellite (TESS). We use Gaia…
SPYGLASS. V. Spatially and Temporally Structured Star-Forming Environments in the Cepheus-Hercules Complex
Ronan Kerr, Adam L. Kraus, Daniel Krolikowski +2
Young associations record complete histories of star forming events through their demographics and dynamics, and Gaia has greatly expanded our knowledge of these associations. We p…
SPYGLASS. IV. New Stellar Survey of Recent Star Formation within 1 kpc
Ronan Kerr, Adam Kraus, Aaron Rizzuto
Young stellar populations provide a powerful record that traces millions of years of star formation history in the solar neighborhood. Using a revised form of the SPYGLASS young st…
SPYGLASS. III. The Fornax-Horologium Association and its Traceback History within the Austral Complex
Ronan Kerr, Adam L. Kraus, Simon J. Murphy +3
The study of young associations is essential for building a complete record of local star formation processes. The Fornax-Horologium association (FH), including the Fornacis…
SPYGLASS. II. The Multi-Generational and Multi-Origin Star Formation History of Cepheus Far North
Ronan Kerr, Adam L. Kraus, Simon J. Murphy +4
Young stellar populations provide a record of past star formation, and by establishing their members' dynamics and ages, it is possible to reconstruct the full history of star form…
TOI-4562 b: A highly eccentric temperate Jupiter analog orbiting a young field star
Alexis Heitzmann, George Zhou, Samuel N. Quinn +47
We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (< Myr). This planet stands o…
TESS Hunt for Young and Maturing Exoplanets (THYME) VII : Membership, rotation, and lithium in the young cluster Group-X and a new young exoplanet
Elisabeth R. Newton, Rayna Rampalli, Adam L. Kraus +36
The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages. These associations enable study of planetary evolution by…
Kepler and the Behemoth: Three Mini-Neptunes in a 40 Million Year Old Association

Stellar positions and velocities from Gaia are yielding a new view of open cluster dispersal. Here we present an analysis of a group of stars spanning Cepheus to Hercules, hereafte…
TESS Hunt for Young and Maturing Exoplanets (THYME) VI: an 11 Myr giant planet transiting a very low-mass star in Lower Centaurus Crux
Andrew W. Mann, Mackenna L. Wood, Stephen P. Schmidt +48
Mature super-Earths and sub-Neptunes are predicted to be Jovian radius when younger than 10 Myr. Thus, we expect to find 5-15 planets around young stars even if t…
