JWST/MIRI Finds ISM-like Amorphous Silicates in Interstellar Comet 3I/ATLAS
Matthew Belyakov, Ian Wong, Carey M. Lisse +7
We present the first spectroscopic mineralogical analysis of the dust coma of an interstellar object (ISO) from JWST mid-infrared spectroscopy of 3I/ATLAS (3I). 3I exhibits a stron…
JWST-TST High Contrast: First Direct Spectroscopy of GJ 504 b reveals Clouds and Possible Metal Enrichment
Aneesh Baburaj, Jean-Baptiste Ruffio, Marshall Perrin +27
Characterizing the coldest directly imaged companions through direct spectroscopy has only recently become possible with the James Webb Space Telescope. We present moderate-resolut…
HD 145263: Spectral Observations of Silica Debris Disk Formation via Extreme Space Weathering?
C. M. Lisse, H. Y. A. Meng, M. L. Sitko +9
We report here time domain infrared spectroscopy and optical photometry of the HD145263 silica-rich circumstellar disk system taken from 2003 through 2014. We find an F4V host star…
Constraints on the gas content of the Fomalhaut debris belt. Can gas-dust interactions explain the belt's morphology?
G. Cataldi, A. Brandeker, G. Olofsson +5
Context: The 440 Myr old main-sequence A-star Fomalhaut is surrounded by an eccentric debris belt with sharp edges. This sort of a morphology is usually attributed to planetary per…
Herschel PACS Observations and Modeling of Debris Disks in the Tucana-Horologium Association
J. K. Donaldson, A. Roberge, C. H. Chen +9
We present Herschel PACS photometry of seventeen B- to M-type stars in the 30 Myr-old Tucana-Horologium Association. This work is part of the Herschel Open Time Key Programme "Gas…
Crystalline silicates and dust processing in the protoplanetary disks of the Taurus young cluster
Dan M. Watson, Jarron M. Leisenring, Elise Furlan +15
We characterize the crystalline silicate content and spatial distribution of small dust grains in a large sample of protoplanetary disks in the Taurus-Auriga young cluster, using S…
