Discovery of an Eccentric Hot Super-Jupiter Leaving the Transiting Geometry of the Early-A-type star TOI-1355

Noriharu Watanabe, Norio Narita, Akihiko Fukui +20

Hot Jupiters orbiting hot stars ( K) are suggested to have experienced high-eccentricity migration, often evidenced by the tendency for misaligned orbits, de…

The Roasting Marshmallows Program with IGRINS on Gemini South V: Atmosphere of MASCARA-1b is Enriched in Refractory Elements

Krishna Kanumalla, Michael R. Line, Martina Chiarella +75

Ultra-hot Jupiters (UHJs; K) enable simultaneous detection of volatile (ice-forming) and refractory (rock-forming) species in planetary atmospheres, provi…

The mass of TOI-1883 b: A low density super-Neptune in the ridge regime transiting an early-M dwarf

Izuru Fukuda, Norio Narita, Akihiko Fukui +36

Recent large-scale transit surveys conducted by space telescopes such as Kepler and TESS have revealed a vast number of exoplanets, uncovering the diversity of their population. On…

WD 1054-226 revisited: a stable transiting debris system

J. Korth, A. J. Mustill, H. Parviainen +24

A growing number of white dwarfs (WDs) exhibit one or more signs of remnant planetary systems, including transits, infrared excesses, and atmospheric metal pollution. WD 1054-226 s…

Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

The mass of TOI-654 b: A short-period sub-Neptune transiting a mid-M dwarf

Kai Ikuta, Norio Narita, Takuya Takarada +40

Sub-Neptunes are small planets between the size of the Earth and Neptune. The orbital and bulk properties of transiting sub-Neptunes can provide clues for their formation and evolu…
