An N-body population synthesis framework for the formation of moons around Jupiter-like planets
Marco Cilibrasi, Judit Szulágyi, Simon L. Grimm +1
The moons of giant planets are believed to form in situ in Circumplanetary Discs (CPDs). Here we present an N-body population synthesis framework for satellite formation around a J…
Refining the transit timing and photometric analysis of TRAPPIST-1: Masses, radii, densities, dynamics, and ephemerides
Eric Agol, Caroline Dorn, Simon L. Grimm +32
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST and K2 transit time measurements, and…
A super-Earth and a sub-Neptune orbiting the bright, quiet M3 dwarf TOI-1266
B. -O. Demory, F. J. Pozuelos, Y. Gomez Maqueo Chew +70
We report the discovery and characterisation of a super-Earth and a sub-Neptune transiting the bright (), quiet, and nearby (37 pc) M3V dwarf TOI-1266. We validate the plane…
Information content of JWST-NIRSPEC transmission spectra of warm Neptunes
Andrea Guzmán-Mesa, Daniel Kitzmann, Chloe Fisher +7
Warm Neptunes offer a rich opportunity for understanding exo-atmospheric chemistry. With the upcoming James Webb Space Telescope (JWST), there is a need to elucidate the balance be…
High-resolution Transmission Spectroscopy of MASCARA-2 b with EXPRES
H. Jens Hoeijmakers, Samuel H. C. Cabot, Lily Zhao +10
We report detections of atomic species in the atmosphere of MASCARA-2 b, using the first transit observations obtained with the newly commissioned EXPRES spectrograph. EXPRES is a…
On the impact of tides on the transit-timing fits to the TRAPPIST-1 system
Emeline Bolmont, Brice-Olivier Demory, Sergi Blanco-Cuaresma +5
Transit Timing Variations, or TTVs, can be a very efficient way of constraining masses and eccentricities of multi-planet systems. Recent measurements of the TTVs of TRAPPIST-1 led…
