The recent result obtained by Givens and Kostinski [J. Mod. Opt. 40, 471 (1993)] successfully solves the old and important problem in polarization optics of...

Ellipsoidal red giant binaries are a particular class of binary stars where the primary gets tidally deformed by the interaction with the companion. They are...

The Owl Nebula is a triple-shell planetary nebula with the outermost shell being a faint bow-shaped halo. We have obtained deep narrowband images and high...

Polytropes have gained renewed interest because they account for several seemingly disconnected observational properties of galaxies. Here we study whether...

Traditionally, the effects of interstellar extinction on binary star light curves have been treated as a uniform reduction in the observed brightness of the...

PHOEBE 2 is a Python package for modeling the observables of eclipsing star systems, but until now it has focused entirely on the forward model—that is...

In this work, we study the gravitational influence of the material extending from Uranus orbit to the Kuiper belt and beyond on objects moving within these...

We present two geometrical methods to analyse the cosmic microwave background data along a strip in the sky. These methods are motivated by the fact that the...

Pisces VII/Triangulum III (Pisc VII) was discovered in the DESI Legacy Imaging Survey and was shown to be a Local Group dwarf galaxy with follow-up imaging from...
