Dust Seeding Molecules in a Massive Protostar -- Detection of TiO in Orion Source I
Ziwei E. Zhang, Nami Sakai, Marcelino Agundez +16
We report the first detection of TiO in star-forming regions based on Atacama Large Millimeter/submillimeter Array observations of Orion Source I, a well-characterized massive prot…
Probing the Innermost Region of the V883 Ori Disk Using ALMA Band 1 Methanol Line Observations
Yoshihide Yamato, Shota Notsu, Rui Zhuang +2
The study uses ALMA Band 1 observations to detect methanol emission lines in the protoplanetary disk around the FU‑Ori star V883 Ori, revealing warm gaseous methanol in the innermo…
CORINOS V: Radiative transfer effects in protostellar ice observations
Will E. Thompson, Jennifer B. Bergner, Neal J. Evans +11
Recent observations of protostars with the James Webb Space Telescope have revealed unprecedented chemical complexity from their ice absorption features. However, these spectra are…
A Chemistry-First Centered Icy Chemical Inventory of Protostellar Sources with JWST
Andrew M. Turner, Yao-Lun Yang, Rachel Gross +2
The chemical evolution in star forming regions is driven by the interplay between gas and ice mantles. Identifying the ice compositions at the early stage of star formation thus pr…
CORINOS IV: Quantifying Baseline-Fitting Uncertainties in SO Ice Measurements with JWST/MIRI
Rachel E. Gross, Yao-Lun Yang, L. Ilsedore Cleeves +15
Sulfur dioxide (SO) ice has been tentatively detected in protostellar envelopes, but its reliability as a solid-state sulfur reservoir remains unclear. We present new measureme…
Observation of CHOH and CHOH in Orion KL: A New Tool to Study Star-Formation History
Yoshimasa Watanabe, Takahiro Oyama, Akemi Tamanai +2
Methanol is a seed species of complex organic molecules that is of fundamental importance in astrochemistry. Although various isotopologues of CHOH have been detected in the in…
