A three-phase approach to grain surface chemistry in protoplanetary disks: Gas, ice surfaces and ice mantles of dust grains
Maxime Ruaud, Uma Gorti
We study the effects of grain surface reactions on the chemistry of protoplanetary disks where gas, ice surface layers and icy mantles of dust grains are considered as three distin…
Astro2020 Science White Paper: Are Supernovae the Dust Producer in the Early Universe?
Jeonghee Rho, Danny Milisavljevic, Arkaprabha Sarangi +23
Whether supernovae are a significant source of dust has been a long-standing debate. The large quantities of dust observed in high-redshift galaxies raise a fundamental question as…
Probing ISM Structure in Trumpler 14 & Carina I Using The Stratospheric Terahertz Observatory 2
Young Min Seo, Paul F. Goldsmith, Chris Walker +26
We present observations of the Trumpler 14/Carina I region carried out using the Stratospheric Terahertz Observatory 2 (STO2). The Trumpler 14/Carina I region is in the west part o…
Searching for stable fullerenes in space with computational chemistry
Alessandra Candian, Marina Gomes Rachid, Heather MacIsaac +3
We report a computational study of the stability and infrared (IR) vibrational spectra of neutral and singly ionised fullerene cages containing between 44 and 70 carbon atoms. The…
