The Effect Of Dynamical Interactions In Stellar Birth Environments On The Orbits Of Young close-in planetary systems
Stars do not form in isolation but together with other stars, and often in a clustered environment. Depending on the initial conditions in these environments, such as initial density and […]

Searching for Neutral Hydrogen Escape from the 120 Myr Old Sub-Neptune HIP94235b using HST
HIP94235 b, a 120 Myr old sub-Neptune, provides us the unique opportunity to study mass loss at a pivotal stage of the system’s evolution: the end of a 100 million […]

Dust-Gas Coupling in Turbulence – and MHD Wind-Driven Protoplanetary Disks: Implications for Rocky Planet Formation
The degree of coupling between dust particles and their surrounding gas in protoplanetary disks is quantified by the dimensionless Stokes number. The Stokes number (St) governs particle size and spatial […]

TESS Discovery of Two Super-Earths Orbiting the M-dwarf Stars TOI-6002 and TOI-5713 Near The Radius Valley
We present the validation of two TESS super-Earth candidates transiting the mid-M dwarfs TOI-6002 and TOI-5713 every 10.90 and 10.44 days, respectively. The first star (TOI-6002) is located 32.038±0.019 pc […]

First Comparative Exoplanetology Within a Transiting Multi-planet System: Comparing the atmospheres of V1298 Tau b and c
The V1298 Tau system (20-30Myr), is a benchmark young multi-planet system that provides the opportunity to perform comparative exoplanetology between planets orbiting the same star right after their formation.

A Larger Sample Confirms Small Planets Around Hot Stars Are Misaligned
The distribution of stellar obliquities provides critical insight into the formation and evolution pathways of exoplanets. In the past decade, it was found that hot stars hosting hot Jupiters are […]
