Searching for substellar companion candidates with Gaia. V. M dwarfs within 15 pc studied with absolute astrometry, radial velocities, and direct imaging

F. Destriez, A. -M. Lagrange, G. Hébrard +10

In this work, we survey M-type stars within 15 pc observed by Gaia based on their colour, magnitude, and quality of astrometric data. We aim to detect new substellar companions usi…

A Misaligned Debris Disk relative to the Host Star CPD-72 2713 from JWST/NIRCam Imaging

Jingwen Zhang, Maxwell A. Millar-Blanchaer, Kellen Lawson +17

Observations of debris disks provide a valuable window to investigate the formation and evolution of planetary systems. We present high-contrast JWST/NIRCam observations of CPD-72…

The JWST Sub-Jupiters Survey: Direct Imaging Discovery of a Giant Planet and a Debris Disk Around the Young M-dwarf RX J0534.0-0221

Rodrigo Ferrer-Chavez, Jason J. Wang, Kevin Wagner +47

We present the discovery of RX J0534.0-0221 b, a giant planet orbiting an M-dwarf star in the Pictoris moving group. RX J0534 was originally observed with JWST/NIRCam in the F4…

The Roman Coronagraph Community Participation Program: early calibration plan and pilot observation of a companion

Julien H. Girard, Eric Cady, Neil T. Zimmerman +42

Roman is set to launch in weeks! The Coronagraph Instrument - technology pathfinder for future direct imaging missions - is ready to fly too. According to predictions, laboratory t…

JWST NIRCam Reveals the Largest Known M-dwarf Debris Disk Around TWA 10 and New Scattered-Light Observations of the TWA 25 Debris Disk

Katie A. Crotts, Aarynn L. Carter, Beth Biller +26

We present JWST NIRCam observations of two M-dwarf systems located in the TW Hydra association, TWA 10 and TWA 25. Both systems harbor detected debris disks in the F200W and F444W…

Follow-Up Exploration of the TWA 7 Planet-Disk System with JWST NIRCam

Katie A. Crotts, Aarynn L. Carter, Kellen Lawson +39

The young M-star TWA 7 hosts a bright and near face-on debris disk, which has been imaged from the optical to the submillimeter. The disk displays multiple complex substructures su…

Probing the Outskirts of M Dwarf Planetary Systems with a Cycle 1 JWST NIRCam Coronagraphy Survey

Ellis Bogat, Joshua E. Schlieder, Kellen D. Lawson +18

The population of giant planets on wide orbits around low-mass M dwarf stars is poorly understood, but the unprecedented sensitivity of JWST NIRCam coronagraphic imaging now provid…

JWST/NIRCam Detection of the Fomalhaut C Debris Disk in Scattered Light

Kellen Lawson, Joshua E. Schlieder, Jarron M. Leisenring +20

Observations of debris disks offer important insights into the formation and evolution of planetary systems. Though M dwarfs make up approximately 80% of nearby stars, very few M-d…

JWST/NIRCam Coronagraphy of the Young Planet-hosting Debris Disk AU Microscopii

Kellen Lawson, Joshua E. Schlieder, Jarron M. Leisenring +20

High-contrast imaging of debris disk systems permits us to assess the composition and size distribution of circumstellar dust, to probe recent dynamical histories, and to directly…
