From Light to Sound: Spectroscopic Evolution & Sonification of the flaring Nova V612 Scuti
Pragati Acharya, Elias Aydi, Kirill V. Sokolovsky +17
We present photometric and spectroscopic observations of the 2017 Galactic nova V612 Sct, whose optical evolution was marked by multiple unusually large maxima. The eruption includ…
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…
TESS detection of periodic brightness variations during the rise of classical nova PGIR22akgylf
Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +14
Classical novae are transient events powered by thermonuclear burning in a layer of hydrogen-rich material accreted by a white dwarf from its binary companion. Most classical novae…
Shocks in the Symbiotic Recurrent Nova V3890 Sgr: VLBI Radio Imaging and Fermi GeV Gamma-Rays
Isabella Molina, Peter Craig, Rebecca Diesing +14
We present very long baseline interferometric (VLBI) radio imaging and Fermi/LAT GeV -ray observations of the 2019 eruption of the symbiotic recurrent nova V3890 Sgr.The VLBI i…
What determines the -ray luminosities of classical novae?
Peter Craig, Elias Aydi, Laura Chomiuk +25
Classical novae in the Milky Way have now been well-established as high-energy GeV -ray sources. In novae with main-sequence companions, this emission is believed to result fro…
Multiple outflows and delayed ejections revealed by early imaging of novae
Elias Aydi, John D. Monnier, Antoine Mérand +39
Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism -- impulsive ejection, multip…
