SU Lyn -- a transient symbiotic star
Krystian Ilkiewicz, Joanna Mikolajewska, Simone Scaringi +3
SU Lyn is a binary system composed of a white dwarf and a red giant star. Although it is known to be bright and variable at X-ray wavelengths, the optical counterpart of the source…
The occurrence of Binary Evolution Pulsators in the classical instability strip of RR Lyrae and Cepheid variables
P. Karczmarek, G. Wiktorowicz, K. Iłkiewicz +5
Single star evolution does not allow extremely low-mass stars to cross the classical instability strip (IS) during the Hubble time. However, within binary evolution framework low-m…
A Survey of the Local Group of Galaxies for Symbiotic Binary Stars. I. First detection of symbiotic stars in M33
Joanna Mikolajewska, Michael M. Shara, Nelson Caldwell +2
We present and discuss initial selection criteria and first results in M33 from a systematic search for extragalactic symbiotic stars. We show that the presence of diffuse interste…
Active phases and flickering of a symbiotic recurrent nova T CrB
Krystian Ilkiewicz, Joanna Mikolajewska, Kiril Stoyanov +2
T CrB is a symbiotic recurrent nova known to exhibit active phases, characterised by apparent increases in the hot component temperature and the appearance of flickering, i.e. chan…
Characterization of the Most Luminous Star in M33: A Super Symbiotic Binary
Joanna Mikolajewska, Nelson Caldwell, Michael M. Shara +1
We present the first spectrum of the most luminous infrared star in M33, and use it to demonstrate that the object is almost certainly a binary composed of a massive O star and a d…
