Companion Architectures of Sub-Saturns: Distinct Migration Pathways Across the Neptunian Landscape

Luis Thomas, Louise D. Nielsen, Alex J. Cridland +2

Close-in sub-Saturns (4 - 8.5 R) are depleted in the Neptunian desert, accumulate in a narrow overdensity near P = 3.2 - 5.7 d (the Neptunian ridge), and thin out into the…

A population view of transiting hot giant exoplanets: Tracing Fe and Ti chemistry with ESPRESSO and MAROON-X

Bibiana Prinoth, Vivien Parmentier, Stefan Pelletier +9

Hot and ultra-hot Jupiters offer a unique laboratory to study atmospheric chemistry at the population level using ground-based high-resolution spectroscopy. Fe and Ti are key trace…

Stellar Obliquities of Young Systems, Atmospheres Undergoing Contraction and Escape (SOYSAUCE) II: a 135 Myr planet on an aligned orbit with transit timing variations

Madyson G. Barber, Andrew W. Mann, Sydney Vach +16

Young planets (<1 Gyr) provide opportunities to directly probe planet formation and evolution processes in action. However, due to heightened stellar activity, there is a lack of k…

Preparing for the Early eVolution Explorer: Detecting the Primordial, Transiting Exoplanet Population

George Zhou, James G. Rogers, Jennifer A. Burt +17

The close-in small planet population may be formed either with hydrogen/helium dominated envelopes or with water-rich interiors. Both scenarios reproduce the present day planet pop…

Exoplanet atmospheres and demographics in the 2040s

Jens Kammerer, Sydney Vach, Sylvestre Lacour +7

Direct observations of exoplanets probe the demographics and atmospheric composition of young self-luminous companions, yielding insight into their formation and early evolution hi…

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…
