Incursiuni în imaginar, 2023 Reality and fiction build a binary which shared the fate of dualist thinking in general in the postmodernist age, dominated by deconstruction. The climactic point was probably reached by the fabrication of lens which magnify reality.

On Variation Mechanisms in Recurrent Nova IM Normae
Galaxies, 2022 Light curves by Woudt and Warner (WW) of recurrent nova IM Nor show eclipse-like dips that they saw as too wide for eclipses alone, and interpreted as mainly a reflection effect due to irradiation of the companion (mass donor) star with some amplitude ...

Parameterization of long-period eclipsing binaries
Open Astronomy, 2022 One of the important sources for independent determination of stellar masses is eclipsing binaries with components on the main sequence, and with observable spectral lines of both components.

Frontiers in Astronomy and Space Sciences, 2021 We present results from an extensive search in the literature and Gaia DR2 for visual co-moving binary companions to stars hosting exoplanets and brown dwarfs within 200 pc.

Constraining the Mass Loss Geometry of Beta Lyrae [PDF]
Journal of Astronomy and Space Sciences, 2012 Massive binary stars lose mass by two mechanisms: jet-driven mass loss during periods of active mass transfer and by wind-driven mass loss. Beta Lyrae is an eclipsing, semi-detached binary whose state of active mass transfer provides a unique ...

Formation of Neutral Disk-Like Zone Around the Active Hot Stars in Symbiotic Binaries
Open Astronomy, 2012 In this contribution we present the ionization structure in the enhanced wind from the hot star in symbiotic binaries during active phases. Rotation of the hot star leads to the compression of the outflowing material towards its equatorial plane.

Mass Ejection from the Symbiotic Prototype Z and During its 2006 Outburst
Open Astronomy, 2012 High-resolution spectroscopic observations in the region of the Balmer Hα and Hγ lines of the symbiotic binary Z And were performed during its major eruption in 2006.

Symbiotic Nova PU Vul - 33 Years of Observations
Open Astronomy, 2012 We present UBVRI light curves of the symbiotic nova PU Vul after its outburst in 1978. Three observed eclipses of the hot component by the cool one were used to determine the ephemeris of the binary system as JD (Min I) = 2444550(15) + 4897(10) × E days.

Photometric Activity of the Symbiotic Star CH Cyg During 2008–2011
Open Astronomy, 2012 We present results of UBVRC observations of the symbiotic star CH Cyg before and after optical and X-ray bursts in 2009 at various timescales. Rapid variability was found only during a strong burst (U ~ 9.5 mag) in 2009 October, while during the low ...

Frontiers in Astronomy and Space Sciences, 2022 The internal motions of the ionized gas in the shells of planetary nebulae (PNe) have served as relevant diagnostic tools to understand the development of this important stage of stellar evolution.
