Mass constraints for the K2-223 system planets: An ultra-short-period sub-Earth, a short-period super-Earth, and a tentative long-period giant planet

Dawid Jankowski, Grzegorz Nowak, Gaia Lacedelli +23

We present mass constraints of two short-period Earth-sized planets transiting K2-223 based on high-precision radial velocity measurements from HARPS-N and ESPRESSO, as well as a t…

The Cephei System: Updated Orbits, Dynamical Architecture, and Limits on Additional Companions

Judah Van Zandt, Brendan P. Bowler, Michael Endl +18

The Cephei system hosts one of the first exoplanets discovered and is orbited by one of the closest known stellar companions to a planet-hosting star. Here, we derive updated o…

A distant brown dwarf coplanar to a warm Jupiter and a hot super-Earth

Matías I. Jones, Luca Naponiello, Trifon Trifonov +21

In transiting planetary systems, in which planetary sizes are accurately determined from transit observations, the presence of transit-timing variations (TTVs), especially when com…

TOI-3862 b: A dense super-Neptune deep in the hot Neptune desert

Ilaria Carleo, Amadeo Castro-González, Enric Pallé +61

The structure and evolution of close-in exoplanets are shaped by atmospheric loss and migration processes, which give rise to key population features such as the hot Neptune desert…

Hipparcos, Gaia, and RVs reveal that the radio emitting F star HD 220242 has an M dwarf companion, a likely source of the radio emission

Megan Delamer, Guðmundur Stefánsson, Suvrath Mahadevan +18

The detection of circularly polarized, low frequency radio emission offers the tantalizing possibility of the observation of interactions between stars and their possible substella…

Precise mass and radius determination for two new and one known Neptune-sized planets around G Dwarf hosts

Ilaria Carleo, Grzegorz Nowak, Felipe Murgas +56

As part of the KESPRINT collaboration, we present the discovery and characterization of three exoplanets in the sub-Neptune to super-Neptune regime, spanning key regions of the exo…
