High-Resolution Transmission Spectroscopy of the Terrestrial Exoplanet GJ 486b

Andrew Ridden-Harper, Stevanus Nugroho, Laura Flagg +11

Terrestrial exoplanets orbiting M-dwarf stars are promising targets for transmission spectroscopy with existing or near-future instrumentation. The atmospheric composition of such…

Planet(esimal)s Around Stars with TESS (PAST) III: A Search for Triplet He I in the Atmospheres of Two 200 Myr-old Planets

Eric Gaidos, Teruyuki Hirano, Rena A. Lee +13

We report a search for excess absorption in the 1083.2 nm line of ortho (triplet) helium during transits of TOI-1807b and TOI-2076b, 1.25 and 2.5R planets on 0.55- an…

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…

Precise mass determination for the keystone sub-Neptune planet transiting the mid-type M dwarf G 9-40

R. Luque, G. Nowak, T. Hirano +45

Context. Despite being a prominent subset of the exoplanet population discovered in the past three decades, the nature and provenance of sub-Neptune-sized planets are still one of…

TOI-1452 b: SPIRou and TESS reveal a super-Earth in a temperate orbit transiting an M4 dwarf

Charles Cadieux, René Doyon, Mykhaylo Plotnykov +53

Exploring the properties of exoplanets near or inside the radius valley provides insights on the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini…

A Super-Earth Orbiting Near the Inner Edge of the Habitable Zone around the M4.5-dwarf Ross 508

Hiroki Harakawa, Takuya Takarada, Yui Kasagi +46

We report the near-infrared radial-velocity (RV) discovery of a super-Earth planet on a 10.77-day orbit around the M4.5 dwarf Ross 508 (). Using precision RVs f…

Coronagraph Experiment on Dark-hole Control by Speckle Area Nulling Method

Masahito Oya, Jun Nishikawa, Masaaki Horie +7

In high-contrast imaging optical systems for direct observation of planets outside our solar system, adaptive optics with an accuracy of lambda/10,000 root mean square is required…

Global Mapping of Surface Composition on an Exo-Earth Using Sparse Modeling

Atsuki Kuwata, Hajime Kawahara, Masataka Aizawa +2

The time series of light reflected from exoplanets by future direct imaging can provide spatial information with respect to the planetary surface. We apply sparse modeling to the r…

Images of Embedded Jovian Planet Formation At A Wide Separation Around AB Aurigae

Thayne Currie, Kellen Lawson, Glenn Schneider +30

Direct images of protoplanets embedded in disks around infant stars provide the key to understanding the formation of gas giant planets like Jupiter. Using the Subaru Telescope and…

TOI-1696: a nearby M4 dwarf with a planet in the Neptunian desert

Mayuko Mori, John H. Livingston, Jerome de Leon +59

We present the discovery and validation of a temperate sub-Neptune around the nearby mid-M dwarf TIC 470381900 (TOI-1696), with a radius of and an orbita…

Dippers from TESS Full-frame Images. II. Spectroscopic Characterization of Four Young Dippers

Yui Kasagi, Takayuki Kotani, Hajime Kawahara +9

Photometric monitoring by the Transiting Exoplanet Survey Satellite (TESS) has discovered not only periodic signals by transiting exoplanets but also episodic or quasi-periodic dim…
