A 9-Month Hubble Space Telescope Near-UV Survey of M87. I. Light and Color Curves of 94 Novae, and a Re-determination of the Nova Rate
Michael M. Shara, Alec M. Lessing, Rebekah Hounsell +10
M87 has been monitored with a cadence of 5 days over a 9 month-long span through the near-ultraviolet (NUV:F275W) and optical (F606W) filters of the Wide Field Camera 3 (WFC3) of t…
Symbiotic star T CrB as an extreme SU UMa type dwarf nova
Krystian Ilkiewicz, Joanna Mikolajewska, Kiril A. Stoyanov
T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases between its classical nova eruptions. The statistical properties of these active phases have been poor…
Chemical abundance analysis of symbiotic giants. Metallicity and CNO abundance patterns in 14 northern S-type systems
Cezary Gałan, Joanna Mikołajewska, Kenneth H. Hinkle +1
In previous works, we computed abundances for the red giant in nearly four dozen S-type symbiotic systems (SySt). The abundances provide information about metallicity, evolutionary…
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…
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…
Shocks in the outflow of the RS Oph 2021 eruption observed with X-ray gratings
Marina Orio, Ehud Behar, Juan Luna +9
The 2021 outburst of the symbiotic recurrent nova RS Oph was observed with the Chandra High Energy Transmission Gratings (HETG) on day 18 after optical maximum and with XMM-Newton…
