DOI: 10.1016/j.newast.2017.01.007
Abstract: Abstract First CCD photometric light curves of the eclipsing binary system 1SWASP J200503.05-343726.5 are presented. Our complete light curves in V, R and I bands using the Bessell filter show an out-of-eclipsing distortion, which means… read more here.

DOI: 10.1038/s41550-020-1037-z
Abstract: White dwarfs are the burnt-out cores of Sun-like stars and are the fate of 97 per cent of the stars in our Galaxy. The internal structure and composition of white dwarfs are hidden by their… read more here.

DOI: 10.1051/0004-6361/202140571
Abstract: Aims. The surface brightness – colour relation (SBCR) is a basic tool in establishing precise and accurate distances within the Local Group. Detached eclipsing binary stars with accurately determined radii and trigonometric parallaxes allow for… read more here.

DOI: 10.1093/mnras/staa1016
Abstract: We present Mon-735, a detached double-lined eclipsing binary (EB) member of the ∼3 Myr old NGC 2264 star-forming region, detected by Spitzer. We simultaneously model the Spitzer light curves, follow-up Keck/HIRES radial velocities, and the… read more here.

DOI: 10.1093/mnras/sty1469
Abstract: Using a time series of high-resolution spectra and high-quality multicolour photometry, we reconstruct surface maps of the primary component of the RS CVn type rapidly rotating eclipsing binary, SV Cam (F9V + K4V). We measure… read more here.
