TESS's First Bound Microlensing Planet: A Binary Microlensing Event Revealing a Planetary Companion toward the Galactic Plane
Mallory Harris, Diana Dragomir, Etienne Bachelet +2
We report the discovery of Gaia23bra b, the first gravitationally bound microlensing planet detected by the Transiting Exoplanet Survey Satellite (TESS). Initially flagged as a sin…
Three long period transiting giant planets from TESS
Rafael Brahm, Solène Ulmer-Moll, Melissa J. Hobson +52
We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single transit events in the…
TOI-4600 b and c: Two long-period giant planets orbiting an early K dwarf
Ismael Mireles, Diana Dragomir, Hugh P. Osborn +31
We report the discovery and validation of two long-period giant exoplanets orbiting the early K dwarf TOI-4600 (V=12.6, T=11.9), first detected using observations from the Transiti…
Separated twins or just siblings? A multi-planet system around an M dwarf including a cool sub-Neptune
Mallory Harris, Diana Dragomir, Ismael Mireles +27
We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS Sector 12 wit…
Characterization of a set of small planets with TESS and CHEOPS and an analysis of photometric performance
Dominic Oddo, Diana Dragomir, Alexis Brandeker +41
The radius valley carries implications for how the atmospheres of small planets form and evolve, but this feature is visible only with highly precise characterizations of many smal…
Securing the legacy of TESS through the care and maintenance of TESS planet ephemerides
Diana Dragomir, Mallory Harris, Joshua Pepper +16
Much of the science from the exoplanets detected by the TESS mission relies on precisely predicted transit times that are needed for many follow-up characterization studies. We inv…
