An analysis of the solar differential rotation in solar cycle No. 19 (1954-1964) determined using Kanzelhoehe sunspot group positions
Ivana Poljancic Beljan, Luka Sibenik, Tomislav Jurkic +7
We study solar differential rotation (DR) for solar cycle No. 19 (1954-1964) by tracing sunspot groups on the sunspot drawings of Kanzelhoehe Observatory for Solar and Environmenta…
The 2018 eruption and long term evolution of the new high-mass Herbig Ae/Be object Gaia-18azl = VES 263
U. Munari, V. Joshi, D. P. K. Banerjee +9
We have been monitoring, at high cadence, the photometric and spectroscopic evolution of VES 263 following the discovery in 2018 of a brightening labeled as event Gaia-18azl. VES 2…
Meridional Motions and Reynolds Stress Determined by Using Kanzelhöhe Drawings and White Light Solar Images from 1964 to 2016
Domagoj Ruždjak, Davor Sudar, Roman Brajša +6
Sunspot position data obtained from Kanzelhöhe Observatory for Solar and Environmental Research (KSO) sunspot drawings and white light images in the period 1964 to 2016 were used t…
Historical light-curve and the 2016 outburst of the symbiotic star StHa 169
U. Munari, M. Graziani, R. Jurdana-Sepic
Accurate BVRI optical photometry of StHa 169 has been collected during the period 2005-2016. It reveals two outbursts, in 2009 and 2016, both peaking at B=13.6. The mean brightness…
The past photometric history of the FU Ori-type young eruptive star 2MASS J06593158-0405277 = V960 Mon
R. Jurdana-Sepic, U. Munari
The known FU Ori-type young eruptive stars are exceedingly rare (a dozen or so confirmed objects) and 2MASS J06593158-0405277, with its 2014 outburst, is likely the latest addition…
Outburst evolution, historic light curve and a flash-ionized nebula around the WZ Sge-type object PNV J03093063+2638031
U. Munari, R. Jurdana-Sepic, P. Ochner +1
We have monitored the 2014 superoutburst of the WZ Sge-type transient PNV J03093063+2638031 for more than four months, from V=11.0 maximum brightness down to V=18.4 mag, close to q…
Optical photometric and spectral study of the new FU Orionis object V2493 Cyg (HBC 722)
E. H. Semkov, S. P. Peneva, U. Munari +7
We present new results from optical photometric and spectroscopic observations of the eruptive pre-main sequence star V2493 Cyg (HBC 722). The object has continued to undergo signi…
Historical light curve and search for previous outbursts of Nova KT Eridani (2009)
R. Jurdana-Sepic, V. A. R. M. Ribeiro, M. J. Darnley +2
Context. Nova Eridani (2009) caught the eye of the nova community due to its fast decline from maximum, which was initially missed, and its subsequent development in the radio and…
The nature and evolution of Nova Cygni 2006
U. Munari, A. Siviero, A. Henden +13
AIMS: Nova Cyg 2006 has been intensively observed throughout its full outburst. We investigate the energetics and evolution of the central source and of the expanding ejecta, their…
Symbiotic stars on Asiago archive plates. II
Ulisse Munari, Rajka Jurdana-Sepic
The Asiago photographic archive has been searched for plates containing the symbiotic stars Hen 2-468, QW Sge, LT Del, V407 Cyg, K 3-9, V335 Vul, FG Ser and Draco C-1. A total of 6…
Symbiotic stars on Asiago archive plates. I
U. Munari, R. Jurdana-Sepic, D. Moro
The rich plate archive of the Asiago observatory has been searched for plates containing the symbiotic stars AS 323, Ap 3-1, CM Aql, V1413 Aql (=AS 338), V443 Her, V627 Cas (=AS 50…
