Optical spectroscopy of Be stars: peak separation of Balmer emission lines
R. K. Zamanov, K. A. Stoyanov, S. Y. Stefanov +2
The Be stars display variable optical emission lines originating in the circumstellar disc. Here we analyse high resolution spectroscopic observations of Be stars and the distance…
The hidden symbiotic star SU Lyn -- detection of flickering in U band
R. K. Zamanov, A. Kostov, M. Moyseev +18
We report photometric observations of the hidden symbiotic star SU Lyn in the optical bands. In five nights we detect a weak flickering in U band with amplitude of about 0.05 magni…
Nova LMC 2009a as observed with XMM-Newton, compared with other novae
Marina Orio, Andrej Dobrotka, Ciro Pinto +9
We examine four high resolution reflection grating spectrometers (RGS) spectra of the February 2009 outburst of the luminous recurrent nova LMC 2009a. They were very complex and ri…
The symbiotic binary ZZ CMi: intranight variability and suggested outbursting nature
R. K. Zamanov, K. A. Stoyanov, A. Kostov +9
We present photometric and spectral observations of the symbiotic star ZZ CMi. We detect intranight variability - flickering and smooth variations in U band. The amplitude of the f…
Evolution of V339 Del (Nova Del 2013) since 0.37 to 75 Days after Discovery
Y. Mueangkon, S. Khamrat, D. Suekong +5
We study the evolution of V339 Del (Nova Del 2013) during 0.37 to 75 days after discovery. Spectra from the Liverpool Telescope were collected and analysed to find velocity of ejec…
Development in Astronomy and Space Science in Africa
Mirjana Pović, Michael Backes, Paul Baki +20
The development of astronomy and space science in Africa has grown significantly over the past few years. These advancements make the United Nations Sustainable Development Goals m…
