A two-component clumpy model for the shell evolution of classical novae: the case of V5668 Sgr

Zulema Abraham, Larissa Takeda, Pedro P. B. Beaklini +4

The shell of the classical nova V5668 Sgr was resolved by ALMA at the frequency of 230 GHz 927 days after eruption, showing that most of the continuum bremsstrahlung emission origi…

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…

Revisiting the classics: On the evolutionary origin of the "Fe II" and "He/N" spectral classes of novae

E. Aydi, L. Chomiuk, J. Strader +21

The optical spectra of novae are characterized by emission lines from the hydrogen Balmer series and either Fe II or He/N, leading to their traditional classification into two spec…

Catching a nova X-ray/UV flash in the visible? Early spectroscopy of the extremely slow Nova Velorum 2022 (Gaia22alz)

E. Aydi, L. Chomiuk, J. Mikołajewska +22

We present early spectral observations of the very slow Galactic nova Gaia22alz, over its gradual rise to peak brightness that lasted 180 days. During the first 50 days, when the n…

The multi-wavelength view of shocks in the fastest nova V1674 Her

K. V. Sokolovsky, T. J. Johnson, S. Buson +41

Classical novae are shock-powered multi-wavelength transients triggered by a thermonuclear runaway on an accreting white dwarf. V1674 Her is the fastest nova ever recorded (time to…

Synchrotron emission from double-peaked radio light curves of the symbiotic recurrent nova V3890 Sagitarii

Miriam M. Nyamai, Justin D. Linford, James R. Allison +4

We present radio observations of the symbiotic recurrent nova V3890 Sagitarii following the 2019 August eruption obtained with the MeerKAT radio telescope at 1.28 GHz and Karl G. J…
