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…
Discovery of a hot, transiting, Earth-sized planet and a second temperate, non-transiting planet around the M4 dwarf GJ 3473 (TOI-488)
J. Kemmer, S. Stock, D. Kossakowski +93
We present the confirmation and characterisation of GJ 3473 b (G 50--16, TOI-488.01), a hot Earth-sized planet orbiting an M4 dwarf star, whose transiting signal ($P=1.1980035\pm0.…
Unified simulations of planetary formation and atmospheric evolution II: Rapid disk clearing by photoevaporation yields low-mass super-Earth atmospheres
Masahiro Ogihara, Masanobu Kunitomo, Yasunori Hori
Super-Earths possess low-mass H/He atmospheres (typically less than 10% by mass). However, the origins of super-Earth atmospheres have not yet been ascertained. We investigate…
The Formation of Jupiter's Diluted Core by a Giant Impact
Shang-Fei Liu, Yasunori Hori, Simon Müller +4
The Juno mission has provided an accurate determination of Jupiter's gravitational field, which has been used to obtain information about the planet's composition and internal stru…
Unified simulations of planetary formation and atmospheric evolution: Effects of pebble accretion, giant impacts, and stellar irradiations on super-Earth formation
Masahiro Ogihara, Yasunori Hori
A substantial number of super-Earths have been discovered, and atmospheres of transiting super-Earths have also been observed by transmission spectroscopy. Several lines of observa…
Do the TRAPPIST-1 Planets Have Hydrogen-rich Atmospheres?
Yasunori Hori, Masahiro Ogihara
Recently, transmission spectroscopy in the atmospheres of the TRAPPIST-1 planets revealed flat and featureless absorption spectra, which rule out cloud-free hydrogen-dominated atmo…
