Two temperate super-Earths transiting a nearby late-type M dwarf
L. Delrez, C. A. Murray, F. J. Pozuelos +82
In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching fo…
Orbital Evolution of Close-in Super-Earths Driven by Atmospheric Escape
Naho Fujita, Yasunori Hori, Takanori Sasaki
The increasing number of super-Earths close to their host stars revealed a scarcity of close-in small planets with 1.5-2.0 in the radius distribution of …
Formation of giant planets with large metal masses and metal fractions via giant impacts in a rapidly dissipating disk
Masahiro Ogihara, Yasunori Hori, Masanobu Kunitomo +1
According to planetary interior models, some giant planets contain large metal masses with large metal-mass fractions. HD 149026b and TOI-849b are characteristic examples of these…
Two Bright M Dwarfs Hosting Ultra-Short-Period Super-Earths with Earth-like Compositions
Teruyuki Hirano, John H. Livingston, Akihiko Fukui +58
We present observations of two bright M dwarfs (TOI-1634 and TOI-1685: ) hosting ultra-short period (USP) planets, identified by the TESS mission. The two stars are simi…
The Linkage between the Core Mass and the Magnetic Field of an Extrasolar Giant Planet from Future Radio Observations
Yasunori Hori
Close-in gas giants are expected to have a strong magnetic field of G. Magnetic fields in extrasolar giant planets are detectable by future radio observations in $\gtr…
Radial-velocity search and statistical studies for short-period planets in the Pleiades open cluster
Takuya Takarada, Bun'ei Sato, Masashi Omiya +2
We report radial-velocity search for short-period planets in the Pleiades open cluster. We observed 30 Pleiades member stars at the Okayama Astrophysical Observatory (OAO) with Hig…
