Dusty Common Envelope Evolution
GalaxiesWe present the first hydrodynamical simulations of common envelope evolution that include the formation of dust and the effect of radiation pressure on dust grains.

Asteroseismic Analysis of δ Scuti Components of Binary Systems: The Case of KIC 8504570
Galaxies, 2020 The present work concerns the Asteroseismology of the Kepler-detached eclipsing binary KIC 8504570. Particularly, it focuses on the pulsational behaviour of the oscillating component of this system and the estimation of its physical parameters in order ...

Correction of UBV Photometry for Emission Lines
Open Astronomy, 2003 We investigate the effect on U,B,V magnitudes of the removal of emission lines from the spectra of some symbiotic stars and novae during their nebular phases.

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 ...

Open Astronomy, 2010 The spectroscopic orbit of a high proper motion star, BD+20 5152, is calculated from 34 CORAVEL-type radial velocity measurements. The star has a slightly eccentric orbit with a period of 5.70613 d, half-amplitude of 47.7 km/s and eccentricity of 0.049 ...

Beyond binaries : a way forward for comparativeeducation
Revista Española de Educación Comparada, 2012 Binary discourses shape and produce the stories we construct about the field of comparative education. In the first part of this article, I review a set of binary discourses that have characterized social science research since the Enlightenment ...

Mass Transfer in Two Post-AGB Binaries with Dusty Disks
Open Astronomy, 2012 We present a time series of high-resolution spectra for two poorly studied candidate post-AGB stars surrounded by dusty disks, BD+46 442 and IRAS 19135+3937. We find that both stars show radial velocity variations with periods of 130-140 days. IRAS 19135+

Features of globular cluster’s dynamics with an intermediate-mass black hole
Open Astronomy, 2018 In this paper, we address the question of how a central intermediate-mass black hole (IMBH) in a globular cluster (GC) affects dynamics, core collapse, and formation of the binary population.

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.

Looking for Signs of Unresolved Binarity in the Continuum of LAMOST Stellar Spectra
GalaxiesWe describe an attempt to derive the binarity rate of samples of 166 A-, F-, G-, and K-type stars from LAMOST DR5 and 1000 randomly selected presumably single stars from Gaia DR3 catalogs.
