The evolution of low-mass, close binary systems with a neutron star component: a detailed grid
(Wiley Blackwell Publishing, Inc, 2012-04)
In close binary systems composed of a normal, donor star and an accreting neutron star, the amount of material received by the accreting component is, so far, a real intrigue. In the literature there are available models ...
Formation of close binaries by triple dynamics in the context of supernovae la progenitors
(Universidad de Valparaíso, 2018-07)
The unique capabilities of Type Ia Supernovae (SN Ia), with emission bright and uniform enough to serve as yardsticks on cosmological distance scales, has resulted in them becoming some of the most important objects in the ...
Fundamental parameters of the eclipsing binary DD CMa and evidence for mass exchange
(IOP Publishing, 2021-04)
We present a detailed photometric and spectroscopic analysis of DD CMa, based on published survey photometry and new spectroscopic data. We find an improved orbital period of Po = 2.0084530(6) days. Our spectra reveal Hβ ...
A Close-in Substellar Object Orbiting the sdOB-type Eclipsing-Binary System NSVS14256825
(National Astronomical Observatories, 2019-09)
NSVS 14256825 is the second sdOB + dM eclipsing binary systems with anorbital period of 2.65 hours. The special binary was reported to contain circumbinary planets or brown dwarfs by using the timing method. However, ...
Speckle Interferometry at SOAR in 2019
(IOP Publishing, 2020)
The results of speckle-interferometric observations at the 4.1 m Southern Astrophysical Research Telescope in 2019 are given, totaling 2555 measurements of 1972 resolved pairs with separations from 15 mas (median 021) and ...
