Accretion Burst Crystallizes Silicates in a Planet-Forming Disk
Jeong-Eun Lee, Chul-Hwan Kim, Jaeyeong Kim +13
Crystalline silicates form at high temperatures (> 900 K; Fabian et al. 2000; Hallenbeck et al. 1998). Their presence in comets (Hanner et al. 1994; Hayward et al. 2000; Wooden et…
EPISODE II: Variability in the CO and HO rovibrational absorption lines in a periodically variable protostar EC 53
Seokho Lee, Jeong-Eun Lee, Chul-Hwan Kim +19
We present two-epoch JWST NIRSpec and MIRI observations of the young protostar EC 53 (V371 Ser), a periodically variable source with well-characterized quiescent and burst phases.…
EPISODE IV: Ice Inventory in the Envelope of EC 53
Jaeyeong Kim, Jeong-Eun Lee, Chul-Hwan Kim +9
We present the 1.628 m spectra of the young protostar EC 53, obtained with JWST NIRSpec IFU and MIRI MRS during the quiescent and burst phases of its periodic brightness vari…
The SPHEREx Ices Investigation: An Overview
Gary J. Melnick, Joseph L. Hora, Matthew L. N. Ashby +26
SPHEREx is a NASA mission designed to perform an all-sky spectroscopic survey in the 0.75 - 5 m wavelength range. Its primary science objectives are to investigate: (1) inflatio…
SPHEREx Wide-Field Infrared Spectral Mapping of Interstellar Ices and Polycyclic Aromatic Hydrocarbons
Joseph L. Hora, Jinyoung K. Noh, Gary J. Melnick +32
We present some of the first infrared spectral maps acquired by SPHEREx. These maps, which to our knowledge are the largest of their type ever compiled in the near-infrared, reveal…
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…
The SPHEREx Satellite Mission
James J. Bock, Asad M. Aboobaker, Joseph Adamo +111
SPHEREx, a NASA explorer satellite launched on 11 March 2025, is carrying out the first all-sky near-infrared spectral survey. The satellite observes in 102 spectral bands from 0.7…
Near- to mid-infrared spectroscopic study of ice analysis using the AKARI/IRC and Spitzer/IRS spectra
Jaeyeong Kim, Jeong-Eun Lee, Chul-Hwan Kim +2
We present the combined 2.530m spectra of four protostars acquired with the infrared camera and the infrared spectrograph on board the AKARI and Spitzer space telescopes, res…
CORINOS. III. Outflow Shocked Regions of the Low-mass Protostellar Source IRAS 15398-3359 with JWST and ALMA
Yuki Okoda, Yao-Lun Yang, Neal J. Evans +10
While molecular outflows have been studied in details with radio interferometry, observations of the hotter gas in protostellar outflows at a comparable physical scale is often cha…
CORINOS II. JWST-MIRI detection of warm molecular gas from an embedded, disk-bearing protostar
Colette Salyk, Yao-Lun Yang, Klaus M. Pontoppidan +8
We present James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI) observations of warm CO and HO gas in emission toward the low-mass protostar IRAS 15398-3359, observ…
