Study of three 2013 novae: V1830 Aql, V556 Ser and V809 Cep
U. Munari, P. Ochner, S. Dallaporta +7
BVRI photometry and low-, medium- and high-resolution Echelle fluxed spectroscopy is presented and discussed for three faint, heavily reddened novae of the FeII-type which erupted…
Formation of a disk structure in the symbiotic binary AX Per during its 2007-10 precursor-type activity
A. Skopal, T. N. Tarasova, Z. Cariková +12
AX Per is an eclipsing symbiotic binary. During active phases, deep narrow minima are observed in its light curve, and the ionization structure in the binary changes significantly.…
The GALAH Survey and Symbiotic Stars. I. Discovery and follow-up of 33 candidate accreting-only systems
U. Munari, G. Traven, N. Masetti +14
We have identified a first group of 33 new candidates for symbiotic stars (SySt) of the accreting-only variety among the 600,255 stars so far observed by the GALAH high-resolution…
Photometry and spectroscopy of the new symbiotic star 2SXPS J173508.4-292958
U. Munari, P. Valisa, A. Vagnozzi +3
We present and discuss the results of our photometric and spectroscopic monitoring of 2SXPS J173508.4-292958 carried out from April to August 2020. This X-ray source, in the foregr…
Atlas of photometric and spectroscopic daily monitoring of the very slow Nova Cas 2021 (=V1405 Cas) during the first 660 days of its outburst
P. Valisa, U. Munari, S. Dallaporta +2
Nova Cas 2021 erupted on 18 March 2021, reaching naked-eye brightness when passing through photometric maximum 53 days later. We describe our ~daily monitoring of its evolution, co…
Persistent nuclear burning in Nova Sgr 2016 N.4 (= V5856 Sgr = ASASSN-16ma) six years past its outburst
U. Munari, N. Masetti, F. M. Walter +4
We report on the fast Nova Sgr 2016 N.4 being surprisingly trapped in a long-lasting and bright plateau (Delta I >= 10 mag above quiescence) six years past the nova eruption. Very…
