The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase

Feng Long, Ilaria Pascucci, Adrien Houge +20

We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16262756.1B (hereafter J0446B), an old (34 Myr) M4.5 star but with hints of ongoing accretion. The sp…

A JWST MIRI MRS View of the Tel Debris Disk and its Brown Dwarf Companion

Yiwei Chai, Christine H. Chen, Kadin Worthen +12

We report JWST MIRI MRS observations of the Pictoris moving group member, Telescopii ( Tel) A and its brown dwarf binary companion, Tel B. Following PSF subtraction,…

An Earth-sized Planet on the Verge of Tidal Disruption

Fei Dai, Andrew W. Howard, Samuel Halverson +95

TOI-6255~b (GJ 4256) is an Earth-sized planet (1.079 ) with an orbital period of only 5.7 hours. With the newly commissioned Keck Planet Finder (KPF) and CARMEN…

MIRI MRS Observations of Beta Pictoris II. The Spectroscopic Case for a Recent Giant Collision

Christine H. Chen, Cicero X. Lu, Kadin Worthen +17

Modeling observations of the archetypal debris disk around Pic, obtained in 2023 January with the MIRI MRS on board JWST, reveals significant differences compared with that obt…

The Aligned Orbit of a Hot Jupiter around the M Dwarf TOI-4201

Tianjun Gan, Sharon X. Wang, Fei Dai +12

Measuring the obliquities of stars hosting giant planets may shed light on the dynamical history of planetary systems. Significant efforts have been made to measure the obliquities…

MIRI MRS Observations of Beta Pictoris I. The Inner Dust, the Planet, and the Gas

Kadin Worthen, Christine H. Chen, David R. Law +15

We present JWST MIRI Medium Resolution Spectrograph (MRS) observations of the Pictoris system. We detect an infrared excess from the central unresolved point source from 5 to 7…

JWST-TST High Contrast: Asymmetries, dust populations and hints of a collision in the Pictoris disk with NIRCam and MIRI

Isabel Rebollido, Christopher C. Stark, Jens Kammerer +21

We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~m provi…
