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…
Interferometric Beam Combination with a Triangular Tricoupler Photonic Chip
Jonah T. Hansen, Michael J. Ireland, Andrew Ross-Adams +4
Beam combiners are important components of an optical/infrared astrophysical interferometer, with many variants as to how to optimally combine two or more beams of light to fringe-…
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…
Three Core-Collapse Supernovae with Nebular Hydrogen Emission
J. Sollerman, S. Yang, S. Schulze +25
We present SN 2020jfo, a Type IIP supernova in the nearby galaxy M61. Optical light curves from the Zwicky Transient Facility, complemented with data from Swift and near-IR photome…
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)…
