The accretion-driven eruption of the recurrent nova T Corona Borealis
Raymundo Baptista, Wagner Schlindwein, Gerardo J. M. Luna
T Corona Borealis (T CrB) is a symbiotic recurrent nova with an yr recurrence interval, the eruptions of which occur on top of a yr long high-brightness sta…
The dwarf nova EX Draconis: a short review
Raymundo Baptista, Wagner Schlindwein
EX Draconis (EX Dra) is a long period dwarf nova showing ~2 mag outburst which lasts for ~7 d and recur on a timescale of (20-30) d. Its deep eclipses allows one to trace the chang…
Modeling the high-brightness state of the recurrent nova T CrB as an enhanced mass-transfer event
Wagner Schlindwein, Raymundo Baptista, Gerardo Juan Manuel Luna
T~Coronae Borealis is the nearest symbiotic recurrent nova. Twice in the last two centuries, in 1866 and 1946, the accreted material ignited on the surface of the white dwarf via r…
Detection of the white-dwarf spin of V1082 Sgr
I. J. Lima, G. Tovmassian, C. V. Rodrigues +9
We report on the discovery of circular polarization modulated with a period of 1.943 +- 0.002 h in the cataclysmic variable V1082 Sgr. These findings unambiguously reveal the rotat…
Mass-transfer Outburts reborn: Modeling the light curve of the dwarf nova EX Draconis
Wagner Schlindwein, Raymundo Baptista
EX Draconis is an eclipsing dwarf nova that shows outbursts with moderate amplitude ( mag) and a recurrence timescale of -30 d. Dwarf novae outbursts are expla…
Challenging the disk instability model: I -- The case of YZ LMi
Raymundo Baptista, Wagner Schlindwein
Observations of YZ LMi show enhanced emission along the stream trajectory beyond impact at disk rim during outbursts as well as when the quiescent disk is large. We investigated wh…
Mapping the accretion disc of the short period eclipsing binary SDSS J0926+3624
Wagner Schlindwein, Raymundo Baptista
We report the analysis of time-series of optical photometry of SDSS J0926+3624 collected with the Liverpool Robotic Telescope between 2012 February and March while the object was i…
