Two temperate Earth- and Neptune-sized planets orbiting fully convective M dwarfs

Madison G. Scott, Georgina Dransfield, Mathilde Timmermans +30

As the diversity of exoplanets continues to grow, it is important to revisit assumptions about habitability and classical HZ definitions. In this work, we introduce an expanded 'te…

A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP

Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53

Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…

Searching for Transit Timing Variations in young transiting systems

Ana Isabel Lopez Murillo, Andrew W. Mann, Madyson G. Barber +3

The discovery of young (<800 Myr) transiting planets has provided a new avenue to explore how planets form and evolve over their lifetimes. Mass measurements for these planets woul…

Stellar Obliquities of Young Systems, Atmospheres Undergoing Contraction and Escape (SOYSAUCE): a likely aligned orbit for the 3 Myr planet TIDYE-1 b

Madyson G. Barber, Andrew W. Mann, Marshall C. Johnson +12

Despite the wide range of planet-star (mis)alignments in the mature population of transiting exoplanets, the small number of known young transiting planets are nearly all aligned w…

TESS Investigation -- Demographics of Young Exoplanets (TI-DYE) IV: a Jovian radius planet orbiting a 34 Myr Sun-like star in the Vela association

Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg +17

The discovery of infant (< 50 Myr), close-in (<30-day period) planets is vital in understanding the formation mechanisms that lead to the distribution of mature transiting planets…

Ever Elusive Exospheres: One Probable Detection and Two Non-Detections of Hα Transits in Young Systems

Reilly P. Milburn, Andrew W. Mann, Keighley Rockcliffe +5

Gaps in the exoplanet population, such as the Neptunian Desert, point to the importance of mass-loss in sculpting the radii of close-in exoplanets. Young planets (500Myr) offer…

High five from ASTEP: Three validated planets and two eclipsing binaries in a diverse set of long-period candidates

Erika Rea, Maximilian N. Günther, George Dransfield +44

We present the analysis of five long-period TESS Objects of Interest (TOIs), all orbiting Sun-like stars, with orbital periods exceeding one month. Initially identified by the Tran…

Migration and Evolution of giant ExoPlanets (MEEP) II: Super-Jupiters and Lithium-rich Host Stars

Jack Schulte, Joseph E. Rodriguez, David W. Latham +30

Although hot Jupiters were the first exoplanets discovered orbiting main sequence stars, the dominant mechanisms through which they form and evolve are not known. To address the qu…
