JWST Reveals Large Reservoirs of Dust and Ongoing Circumstellar Interaction in SN Ibn/Icn 2023xgo over a Year Post-Explosion
Kyle W. Davis, Kirsty Taggart, Samaporn Tinyanont +23
We present infrared (IR) photometric and spectroscopic observations of SN 2023xgo, a recent and nearby Type Ibn/Icn supernova (SN Ibn/Icn) which shows shock interaction with a He/C…
Detection of a molecular hydrogen envelope around nova GK Persei
D. P. K. Banerjee, A. Evans, T. Liimets +4
The eruption of Nova Persei 1901 (GK Per) occurred 125 yrs ago; remarkably it still holds major surprises. Using data from the Spectro-Photometer for the History of the Universe, E…
Near-Infrared and Optical Observations of SN 2024rbc: The First Early Detection of CO and Dust in a Type Ib Supernova
Ryan Hwangbo, Jeonghee Rho, Aravind P. Ravi +16
We present optical and near-infrared (NIR) observations of the Type Ib supernova (SN) 2024rbc. Emission from the first CO overtone, resting on a dust continuum at m, w…
An infrared echo from a circumstellar disk in the hydrogen- and helium-poor SN 2024aecx
Samaporn Tinyanont, Kittipong Wangnok, Jennifer E. Andrews +34
We present near-infrared (NIR) spectroscopy of the hydrogen- and helium-poor (Type Ic) supernova (SN) 2024aecx, which displays a strong NIR excess emerging 32 days post peak. SN 20…
The [Fe XIII] Infrared 10747 Angstrom and 10798 Angstrom Lines in Novae
D. P. K. Banerjee, C. E. Woodward, A. Evans +3
The forbidden lines of [Fe XIII] at 10,747 Angstrom and 10,798 Angsrtom are among the most prominent lines in the near-infrared spectrum of the solar corona. They have been used ro…
Newborn jet in the symbiotic system R Aquarii
T. Liimets, D. P. K. Banerjee, M. Santander-García +12
R Aquarii (R Aqr) is a well-known symbiotic binary that has attracted renewed interest during its recent periastron passage, an event that occurs only once every about 40 years. Th…
A Tale of Two Sightlines: Comparison of Hydrocarbon Dust Absorption Bands toward Cygnus OB2-12 and the Galactic Center
Yvonne J. Pendleton, T. R. Geballe, Laurie E. U. Chu +14
Infrared spectra of hydrocarbon dust absorption bands toward the bright hypergiant Cygnus OB2-12 are compared to published spectra of the Quintuplet Cluster, a sightline to the Gal…
Near-Infrared Spectroscopy and Detection of Carbon Monoxide in the Type II Supernova SN 2023ixf
Seong Hyun Park, Jeonghee Rho, Sung-Chul Yoon +33
Core-collapse supernovae (CCSNe) may contribute a significant amount of dust in the early universe. Freshly formed coolant molecules (e.g., CO) and warm dust can be found in CCSNe…
Infrared Spectroscopy of V838 Monocerotis in 2015 and 2022
T. R. Geballe, B. M. Kaminskiy, D. P. K. Banerjee +5
We report medium-resolution m spectroscopy obtained in 2015 and 2022 and high resolution m and m spectroscopy obtained in 2015 of V838 Mon…
Investigating silicate, carbon, and water in the diffuse interstellar medium: the first shots from WISCI
S. T. Zeegers, Jonathan P. Marshall, Karl D. Gordon +33
The dusty interstellar medium (ISM) of the Milky Way is distributed in a complex, cloudy structure. It is fundamental to the radiation balance within the Milky Way, provides a reac…
Near-Infrared Spectroscopy of the Recurrent Nova M31N 2008-12a
D. P. K. Banerjee, T. R. Geballe, A. Evans +3
Near infrared (NIR) 0.9--2.5m spectra of the remarkable recurrent nova M31N 2008-12a were obtained on days 6.3 and 10.3 after discovery of its 2024 outburst, and are the first N…
R Coronae Borealis and dustless Hydrogen-deficient Carbon stars have different oxygen isotope ratios
Viraj Karambelkar, Mansi Kasliwal, Patrick Tisserand +5
R Coronae Borealis (RCB) and dustless Hydrogen-deficient Carbon (dLHdC) stars are believed to be remnants of low mass white dwarf mergers. These supergiant stars have peculiar hydr…
Sakurai's Object: characterising the near-infrared CO ejecta between 2003 and 2007
H L. Worters, M. T. Rushton, S. P. S. Eyres +2
We present observations of Sakurai's Object obtained at 1-5um between 2003 and 2007. By fitting a radiative transfer model to an echelle spectrum of CO fundamental absorption featu…
Metallicity in the Galactic Center: The Quintuplet cluster
Francisco Najarro, Don F. Figer, D. John Hillier +2
We present a measurement of metallicity in the Galactic center Quintuplet Cluster made using quantitative spectral analysis of two Luminous Blue Variables (LBVs). The analysis empl…
