Optical and NIR data and modelling of nova V5668 Sgr

L. Takeda, M. Diaz, R. D. Campbell +4

We present HST optical images, Keck-OSIRIS NIR IFS data cubes and Keck-NIRC2 NIR images of nova V5668 Sgr from 2016 to 2019. The observations indicate enhanced emission at the pola…

Two close binaries across the hydrogen-burning limit in the Praesepe open cluster

N. Lodieu, C. del Burgo, E. Manjavacas +7

We present Keck I/OSIRIS and Keck II/NIRC2 adaptive optics imaging of two member candidates of the Praesepe stellar cluster (d=186.180.11 pc; 590-790 Myr), UGC J08451066+21481…

A Potential Progenitor for the Type Ic Supernova 2017ein

Charles D. Kilpatrick, Tyler Takaro, Ryan J. Foley +9

We report the first detection of a credible progenitor system for a Type Ic supernova (SN Ic), SN 2017ein. We present spectra and photometry of the SN, finding it to be similar to…

3D photoionization models of nova V723 Cas

L. Takeda, M. Diaz, R. Campbell +1

We present modeling and analysis of the ejecta of nova V723 Cas based on spatially resolved IR spectroscopic data from Keck-OSIRIS, with LGSAO (adaptive optics module). The 3D phot…

Phase-Resolved Infrared Spectroscopy and Photometry of V1500 Cygni, and a Search for Similar Old Classical Novae

Thomas E. Harrison, Randy D. Campbell, James E. Lyke

We present phase-resolved near-infrared photometry and spectroscopy of the classical nova V1500 Cyg to explore whether cyclotron emission is present in this system. While the spect…
