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 Melicherčík
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 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…
The RS Oph outburst of 2021 monitored in X-rays with NICER
Marina Orio, Keith Gendreau, Morgan Giese +19
The 2021 outburst of the symbiotic recurrent nova RS Oph was monitored with the Neutron Star Interior Composition Explorer Mission (NICER) in the 0.2-12 keV range from day one afte…
Recurrent mini-outbursts and a magnetic white dwarf in the symbiotic system FN Sgr
J. Magdolen, A. Dobrotka, M. Orio +5
AIMS: We investigated the optical variability of the symbiotic binary FN Sgr, with photometric monitoring during 55 years and with a high-cadence Kepler light curve lasting…
High Resolution X-ray Spectra of RS Ophiuchi (2006 and 2021): Revealing the cause of SSS variability
J. -U. Ness, A. P. Beardmore, M. F. Bode +9
Swift observed the SSS phase in RS Oph much fainter in 2021 than in 2006, and we compare an XMM-Newton grating spectrum on day 55.6 in 2021 (2021d55.6) to SSS Chandra and XMM-Newto…
NICER monitoring of supersoft X-ray sources
M. Orio, K. Gendreau, M. Giese +9
We monitored four supersoft sources - two persistent ones, CAL 83 and MR Vel, and the recent novae YZ Ret (Nova Ret 2020) and V1674 Her (Nova Her 2021) - with NICER. The two persis…
