The dawn of a new era for dustless HdC stars with GAIA eDR3
P. Tisserand, C. L. Crawford, G. C. Clayton +7
Decades after their discovery, only four hydrogen-deficient carbon (HdC) stars were known to have no circumstellar dust shell. This is in complete contrast to the 130 known G…
Second Timescale Photometry of the Very Fast Nova V1674 Her with Palomar Gattini-IR
Kylie Y. Hansen, Kishalay De, Michael C. B. Ashley +15
We report second-timescale infrared photometry of the nova V1674 Her using Palomar Gattini-IR. These observations constitute the first infrared and highest temporal resolution data…
PGIR 20eid (SN2020qmp): A Type IIP Supernova at 15.6 Mpc discovered by the Palomar Gattini-IR survey
G. P. Srinivasaragavan, I. Sfaradi, J. Jencson +19
We present a detailed analysis of SN 2020qmp, a nearby type IIP core-collapse supernova (CCSN), discovered by the Palomar Gattini-IR (PGIR) survey in the galaxy UGC07125. We illust…
Discovery of a 310-day Period from the Enshrouded Massive System NaSt1 (WR 122)
Ryan M. Lau, Samaporn Tinyanont, Matthew J. Hankins +15
We present optical and infrared (IR) light curves of NaSt1, also known as Wolf-Rayet (WR) 122, with observations from Palomar Gattini-IR (PGIR), the Zwicky Transient Facility (ZTF)…
A population of heavily reddened, optically missed novae from Palomar Gattini-IR: Constraints on the Galactic nova rate
Kishalay De, Mansi M. Kasliwal, Matthew J. Hankins +25
The nova rate in the Milky Way remains largely uncertain, despite its vital importance in constraining models of Galactic chemical evolution as well as understanding progenitor cha…
