A very rapidly rotating white dwarf in nova YZ Reticuli
G. J. M. Luna, N. Rawat, R. Angeloni +4
YZ Ret (Nova Reticuli 2020) is the first VY Scl-type nova-like variable observed to undergo a classical nova eruption. Following the outburst, timing analysis of 20-s cadence TESS…
A TESS View of Post-Eruption Variability in the Novae V1405 Cas,V1716 Sco, and V1674 Her
G. J. M. Luna, A. Dobrotka, M. Orio
We analyzed TESS archival data of three novae after recent outbursts, searching the orbital and white dwarf (WD) rotation period and possible variations of these periods. In V1405…
X-ray Observations of Nova Scorpii 2023 (V1716 Sco) in Outburst
John Worley, Marina Orio, Andrej Dobrotka +5
Nova Scorpii 2023 was first detected as a luminous supersoft X-ray source (SSS) 93 days after outburst and continued emitting soft X-rays for over two months, until it was too clos…
Hunt for the mHz variability in the TESS and XMM-Newton observations of nova-like cataclysmic variables
Andrej Dobrotka, Jozef Magdolen, Martin MelicherÄÃk
We analysed the flickering of selected nova-like cataclysmic variables observed by the TESS satellite and XMM-Newton. We searched for break frequencies () in the corresp…
Searching for similarities in the accretion flow of Seyfert 1 galaxies and cataclysmic variables based on flare profiles of IRAS 13224-3809, 1H 0707-495, Mrk 766 and MV Lyr
A. Dobrotka, H. Negoro, P. Bezak
AIMS: We studied fast variability of three selected AGNs, IRAS 13224-3809, 1H 0707-495 and Mrk 766, and the cataclysmic variable MV Lyr observed by XMM-Newton and Kepler spacecraft…
Searching for the mHz variability in the TESS observations of nova-like cataclysmic variables
A. Dobrotka, J. Magdolen, D. Janikova
AIMS: We investigated fast optical variability of selected nova-like cataclysmic variables observed by TESS satellite. We searched for break frequencies (f_b) in the corresponding…
