Japan's Possible Contributions for Coronagraph of the Habitable Worlds Observatory (HWO)

Keigo Enya, Kenta Yoneta, Naoshi Murakami +20

In this paper, we describe Japan's possible contributions for coronagraph of the Habitable Worlds Observatory (HWO) based on our independent study. We are considering to contribute…

The Orbital Eccentricity--Radius Distribution for Warm, Single Planets in TESS

Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang +40

We characterize the radius-dependent eccentricity distribution of 219 warm (P = 8--50 days) systems with only one transiting planetary candidate identified during Sectors 1-69 of t…

Direct Imaging Explorations for Companions from the Subaru/IRD Strategic Program II; Discovery of a Brown-dwarf Companion around a Nearby mid-M~dwarf LSPM~J1446+4633

Taichi Uyama, Masayuki Kuzuhara, Charles Beichman +35

We report the discovery of a new directly-imaged brown dwarf companion with Keck/NIRC2+pyWFS around a nearby mid-type M~dwarf LSPM~J1446+4633 (hereafter J1446). The -band contr…

Confirmation of four hot Jupiters detected by TESS using follow-up spectroscopy from MaHPS at Wendelstein together with NEID and TRES

Juliana Ehrhardt, Luis Thomas, Hanna Kellermann +57

We report the confirmation and characterization of four hot Jupiter-type exoplanets initially detected by TESS: TOI-1295 b, TOI-2580 b, TOI-6016 b, and TOI-6130 b. Using observatio…
