SPHEREx as a frontier for infrared transients: Classification of new Galactic FU Ori outbursts and classical novae
Viraj Karambelkar, Kishalay De, Lynne A. Hillenbrand +3
We demonstrate proof-of-concept of a new strategy for studying infrared (IR) transients enabled by the newly launched SPHEREx space mission, by leveraging its synergy with the NEOW…

TESS photometry of the nova eruption in V606 Vul: asymmetric photosphere and multiple ejections?
Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +70
Lightcurves of many classical novae deviate from the canonical "fast rise - smooth decline" pattern and display complex variability behavior. We present the first TESS-space-photom…

The first Palomar Gattini-IR catalog of J-band light curves: construction and public data release
Shion Murakawa, Kishalay De, Michael C. B. Ashley +7
Palomar Gattini-IR (PGIR) is a wide-field, synoptic infrared time domain survey covering \,sq.\,deg. of the \textbf{accessible} sky at \,night cadence t…
