Pre-nova Observations of T CrB: A view from the CHARA Array
Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38
T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…
Near-infrared spectroscopy of RS Ophiuchi in 2021: the calm, the storm, and the abatement
C. E. Woodward, A. Evans, D. P. K. Banerjee +4
We present near-infrared (NIR) observations of the 2021 eruption of the recurrent nova RS Ophiuchi. The dataset provides both pre- and post-eruption perspectives on the eruption, a…
Evidence for the merger hypothesis in V4332 Sgr: a low C/C ratio and multiple outbursts
D. P. K. Banerjee, A. Evans, Watson P. Varricatt +1
Following the detections of the first extragalactic ``Luminous Red Nova'' (LRN) M31 RV in 1989, and its first Galactic counterpart V4332~Sgr in 1994, there have been many discoveri…
The [Fe XIII] Infrared 10747 Angstrom and 10798 Angstrom Lines in Novae
D. P. K. Banerjee, C. E. Woodward, A. Evans +3
The forbidden lines of [Fe XIII] at 10,747 Angstrom and 10,798 Angsrtom are among the most prominent lines in the near-infrared spectrum of the solar corona. They have been used ro…
Newborn jet in the symbiotic system R Aquarii
T. Liimets, D. P. K. Banerjee, M. Santander-GarcÃa +12
R Aquarii (R Aqr) is a well-known symbiotic binary that has attracted renewed interest during its recent periastron passage, an event that occurs only once every about 40 years. Th…
Infrared Spectroscopy of V838 Monocerotis in 2015 and 2022
T. R. Geballe, B. M. Kaminskiy, D. P. K. Banerjee +5
We report medium-resolution m spectroscopy obtained in 2015 and 2022 and high resolution m and m spectroscopy obtained in 2015 of V838…
