Cerium features in kilonova near-infrared spectra: implication from a chemically peculiar star

Masaomi Tanaka, Nanae Domoto, Wako Aoki +14

Observations of the kilonova from a neutron star merger event GW170817 opened a way to directly study r-process nucleosynthesis by neutron star mergers. It is, however, challenging…

A spectroscopic thermometer: individual vibrational band spectroscopy with the example of OH in the atmosphere of WASP-33b

Sam O. M. Wright, Stevanus K. Nugroho, Matteo Brogi +26

Individual vibrational band spectroscopy presents an opportunity to examine exoplanet atmospheres in detail by distinguishing where the vibrational state populations of molecules d…

The mass determination of TOI-519 b: a close-in giant planet transiting a metal-rich mid-M dwarf

Taiki Kagetani, Norio Narita, Tadahiro Kimura +33

We report the mass determination of TOI-519 b, a transiting substellar object around a mid-M dwarf. We carried out radial velocity measurements using Subaru / InfraRed Doppler (IRD…

Absence of extended atmospheres in low-mass star radius-gap planets GJ 9827 b, GJ 9827 d and TOI-1235 b

Vigneshwaran Krishnamurthy, Teruyuki Hirano, Eric Gaidos +20

\textit{Kepler} showed a paucity of planets with radii of 1.5 - 2 around solar mass stars but this radius-gap has not been well studied for low-mass star plane…

An Earth-sized Planet around an M5 Dwarf Star at 22 pc

Teruyuki Hirano, Fei Dai, John H. Livingston +46

We report on the discovery of an Earth-sized transiting planet () in a day orbit around K2-415 (EPIC 211414619), an M5V star at 22 pc. The pla…
