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…
Infrared photometry of the dwarf nova V2051 Ophiuchi: II -- The quiescent accretion disc and its spiral arms
Raymundo Baptista, Eduardo Wojcikiewicz
We report the analysis of time-series of infrared photometry of the dwarf nova V2051 Oph in quiescence with eclipse mapping techniques to investigate structures and the spe…
VVV-WIT-07: another Boyajian's star or a Mamajek's object?
Roberto K. Saito, Dante Minniti, Valentin D. Ivanov +6
We report the discovery of VVV-WIT-07, an unique and intriguing variable source presenting a sequence of recurrent dips with a likely deep eclipse in July 2012. The object was foun…
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…
Infrared photometry of the dwarf nova V2051 Ophiuchi: I - The mass donor star and the distance
Eduardo Wojcikiewicz, Raymundo Baptista, Tiago Ribeiro
We report the analysis of time-series of infrared photometry of the dwarf nova V2051 Oph in quiescence. We modelled the ellipsoidal variations caused by the distorted mass-…
SOAR observations of the high-viscosity accretion disc of the dwarf nova V4140 Sagitarii in quiescence and in outburst
Raymundo Baptista, Bernardo W. Borges, Alexandre S. Oliveira
We report the analysis of 22 B-band light curves of the dwarf nova V4140 Sgr obtained with SOI/SOAR during two nights along the decline of a superoutburst in 2006 Sep 12-24 and in…
