Laboratory study of the torus instability threshold in solar-relevant, line-tied magnetic flux ropes
Andrew Alt, Clayton E. Myers, Hantao Ji +7
Coronal mass ejections (CME) occur when long-lived magnetic flux ropes (MFR) anchored to the solar surface destabilize and erupt away from the Sun. This destabilization is often de…
Eruptions from coronal hole bright points: observations and non-potential modelling
Maria S. Madjarska, Klaus Galsgaard, Duncan H. Mackay +2
A single case study of a CBP in an equatorial coronal hole with an exceptionally large size is investigated to extend our understanding of the formation of mini-filaments, their de…
New insights on the massive interacting binary UU Cassiopeiae
R. E. Mennickent, G. Djurašević, I. Vince +7
We present the results of the study of the close binary UU Cassiopeiae based on previously published multi wavelength photometric and spectroscopic data. Based on eclipse timings o…
BV(RI)c photometric study of three variable PMS stars in the field of V733 Cephei
Sunay Ibryamov, Evgeni Semkov, Stoyanka Peneva +1
This paper report results from the first long-term BV(RI)c photometric CCD observations of three variable pre-main-sequence stars collected during the period from February 2007 to…
Optical spectroscopy and X-ray observations of the D-type symbiotic star EF Aql
K. A. Stoyanov, K. Iłkiewicz, G. J. M. Luna +6
We performed high-resolution optical spectroscopy and X-ray observations of the recently identified Mira-type symbiotic star EF Aql. Based on high-resolution optical spectroscopy o…
A global view on the colliding-wind binary WR 147
Svetozar A. Zhekov, Blagovest V. Petrov, Toma V. Tomov +1
We present results from a global view on the colliding-wind binary WR 147. We analysed new optical spectra of WR 147 obtained with Gran Telescopio CANARIAS and archive spectra from…
Flickering of the jet-ejecting symbiotic star MWC 560
R. K. Zamanov, S. Boeva, K. A. Stoyanov +4
We analyse optical photometric data of short term variability (flickering) of the accreting white dwarf in the jet-ejecting symbiotic star MWC560. The observations are obtained in…
International observational campaign of the 2014 eclipse of EE Cep
D. Pieńkowski, C. Gałan, T. Tomov +64
Context. EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to ε Aur. The system is characterized by grey and asymmetric eclip…
