JWST Spectra Indicate a Large Mass of Postshock Dust Formed by SN 2010jl
Nathan Smith, Melissa Shahbandeh, Ori D. Fox +22
The paper reports JWST mid‑infrared spectra of the Type IIn supernova SN 2010jl 13 years after explosion, revealing a large (~0.2 M☉) mass of warm dust formed in the post‑shock reg…
Identifying Gems from Roman RAPIDly
Karan Gandhi, Ashish A. Mahabal, Jacob E. Jencson +6
The Nancy Grace Roman Space Telescope (Roman), set for launch as early as September 2026, will conduct wide-field infrared imaging surveys with unprecedented spatial resolution and…
The Progenitor of the Type II-Plateau SN 2025pht in NGC 1637: The Dustiest, Most Luminous Red Supergiant So Far?
Schuyler D. Van Dyk, Tamas Szalai, Gagandeep S. Anand +14
We provide a characterization of the red supergiant (RSG) progenitor candidate for the nearby Type II-plateau supernova (SN) 2025pht in NGC 1637. The star was first detectable in 2…
Two Decades of Dust Evolution in SN 2005af through JWST, Spitzer, and Chemical Modeling
Arkaprabha Sarangi, Szanna Zsiros, Tamas Szalai +20
The evolution of dust in core-collapse supernovae (SNe), in general, is poorly constrained owing to a lack of infrared observations after a few years from explosion. Most theories…
The Demographics of Binary Companions to Stripped-Envelope Supernovae: Confronting Observations with Population Synthesis
E. Zapartas, O. D. Fox, J. Su +15
Stripped-envelope supernovae (SESNe) mark the deaths of massive stars without hydrogen-rich envelopes. Most SESNe likely originate from binary systems where a companion stripped th…
Red Supergiants as Supernova Progenitors
Schuyler D. Van Dyk
The inevitable fate of massive stars in the initial mass range of ~8--30 M_{Sun} in the red supergiant (RSG) phase is a core-collapse supernova (SN) explosion, although some stars…
