An optical--mid-infrared color evolution tool for nova identification using WISE data
Joseph Onuegbu, Dafne Guetta, Yael Hillman +2
We present a novel approach for characterizing nova candidates by exploiting the infrared capabilities of the Wide-field Infrared Survey Explorer (WISE) catalog. We developed a pip…
An updated catalog of HIRES/Keck radial velocity measurements. Including Ca II H&K measurements
Jerusalem T. Teklu, Volker Perdelwitz, R. Paul Butler +4
The first HIRES/Keck precision radial velocity (RV) catalog was released in 2017; it was followed by a second release in 2019, which incorporated corrections for small but signific…
On the light-curves of disk and bulge novae
Asaf Cohen, Dafne Guetta, Yael Hillman +4
We examine the light curves of a sample of novae, classifying them into single-peaked and multiple-peaked morphologies. Using accurate distances from Gaia, we determine the spatial…
Potential Interior Structures and Habitability of Super-Earth Exoplanets LHS 1140 b, K2-18 b, TOI-1452 b and TOI-1468 c
Mangesh Daspute, Amri Wandel, Ravi Kumar Kopparapu +3
We analyze four super-Earth exoplanets, LHS 1140 b, K2-18 b, TOI-1452 b, and TOI-1468 c, which orbit M-dwarf stars in the habitable zone. Their relative proximity, within 40 parsec…
