We report JWST MIRI MRS observations of the $\beta$ Pictoris moving group member, $\eta$ Telescopii ($\eta$ Tel) A and its brown dwarf binary companion, $\eta$ Tel B. Following PSF subtraction, we recover the spatially resolved flux from the debris d

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

Autor: Chen, Christine H., Lu, Cicero X., Worthen, Kadin, Law, David R., Sargent, B. A., Moro-Martin, Amaya, Sloan, G. C., Lisse, Carey M., Watson, Dan M., Girard, Julien H., Chai, Yiwei, Hines, Dean C., Kammerer, Jens, Li, Alexis, Perrin, Marshall, Pueyo, Laurent, Rebollido, Isabel, Stapelfeldt, Karl R., Stark, Christopher, Werner, Michael W.

Modeling observations of the archetypal debris disk around $\beta$ Pic, obtained in 2023 January with the MIRI MRS on board JWST, reveals significant differences compared with that obtained with the IRS on board Spitzer. The bright 5 - 15 $\mu$m cont

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

Autor: Worthen, Kadin, Chen, Christine H., Law, David R., Lu, Cicero X., Hoch, Kielan, Chai, Yiwei, Sloan, G. C., Sargent, B. A., Kammerer, Jens, Hines, Dean C., Rebollido, Isabel, Balmer, William O., Perrin, Marshall D., Watson, Dan M., Pueyo, Laurent, Girard, Julien H., Lisse, Carey M., Stark, Christopher C.

We present JWST MIRI Medium Resolution Spectrograph (MRS) observations of the $\beta$ Pictoris system. We detect an infrared excess from the central unresolved point source from 5 to 7.5 $\mu$m which is indicative of dust within the inner $\sim$7 au

We present high-spectral resolution M-band spectra from iSHELL on NASA's Infrared Telescope Facility (IRTF) along the line of sight to the debris disk host star HD 32297. We also present a Gemini Planet Imager (GPI) H-band polarimetric image of the H

We present aperture masking interferometry (AMI) observations of the star HIP 65426 at $3.8\,\rm{\mu m}$ as a part of the JWST Direct Imaging Early Release Science (ERS) program obtained using the Near Infrared Imager and Slitless Spectrograph (NIRIS
