Water Enrichment from Pebble Drift in Disks with Gap-forming Planets
Whittney Easterwood, Anusha Kalyaan, Andrea Banzatti
Volatiles like are present as ice in solids in the outer cold regions of protoplanetary disks and as vapor in the warm inner regions within the water snow line. Icy pebbles…
Water-Rich Disks around Late M-stars Unveiled: Exploring the Remarkable Case of Sz114
Chengyan Xie, Ilaria Pascucci, Feng Long +18
We present an analysis of the JDISC JWST/MIRI-MRS spectrum of Sz~114, an accreting M5 star surrounded by a large dust disk with a shallow gap at au. The spectrum is molec…
High-contrast JWST-MIRI spectroscopy of planet-forming disks for the JDISC Survey
Klaus M. Pontoppidan, Colette Salyk, Andrea Banzatti +26
The JWST Disk Infrared Spectral Chemistry Survey (JDISCS) aims to understand the evolution of the chemistry of inner protoplanetary disks using the Mid-InfraRed Instrument (MIRI) o…
The Effect of Dust Evolution and Traps on Inner Disk Water Enrichment
Anusha Kalyaan, Paola Pinilla, Sebastiaan Krijt +6
Substructures in protoplanetary disks can act as dust traps that shape the radial distribution of pebbles. By blocking the passage of pebbles, the presence of gaps in disks may hav…
JWST reveals excess cool water near the snowline in compact disks, consistent with pebble drift
Andrea Banzatti, Klaus M. Pontoppidan, John Carr +19
Previous analyses of mid-infrared water spectra from young protoplanetary disks observed with the Spitzer-IRS found an anti-correlation between water luminosity and the millimeter…
Linking Outer Disk Pebble Dynamics and Gaps to Inner Disk Water Enrichment
A. Kalyaan, P. Pinilla, S. Krijt +2
Millimeter continuum imaging of protoplanetary disks reveals the distribution of solid particles and the presence of substructures (gaps and rings) beyond 5-10 au, while infrared (…
Effect of Different Angular Momentum Transport mechanisms on the Distribution of Water in Protoplanetary Disks
Anusha Kalyaan, Steven J. Desch
The snow line in a protoplanetary disk demarcates regions with HO ice from regions with HO vapor. Where a planet forms relative to this location determines how much water a…
Development of a Lunar Scintillometer as part of the National Large Optical Telescope Site Survey
Avinash Surendran, Padmakar S. Parihar, Ravinder K Banyal +1
Ground layer turbulence is a very important site characterization parameter used to assess the quality of an astronomical site. The Lunar Scintillometer is a simple and effective s…
The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites
Steven J. Desch, Anusha Kalyaan, Conel M. O'D. Alexander
We present a comprehensive evolutionary model of the Sun's protoplanetary disk, constructed to resolve the "CAI Storage" problem of meteoritics. We predict the abundances of calciu…
Formulas for Radial Transport in Protoplanetary Disks
Steven J. Desch, Paul R. Estrada, Anusha Kalyaan +1
Quantification of the radial transport of gaseous species and solid particles is important to many applications in protoplanetary disk evolution. An especially important example is…
Lately Exposed Amorphous Water Ice on Comet 49P/Arend-Rigaux
B. Sivaraman, V. Venkataraman, A. Kalyaan +2
Comet 49P/ Arend-Rigaux, thought to be a low activity comet since the 1980's was found to be active in its recent apparitions. Recent analysis of the data obtained from Spitzer obs…
