KIC 9832227 is a contact binary whose 11 hr orbital period is rapidly changing. Based on the apparent exponential decay of its period, the two stars were predicted to merge in early 2022 resulting in a rare red nova outburst. Fortunately KIC 9832227 was observed in 2003 as part of the NASA Ames pre-Kepler Vulcan Project to search for transiting exoplanets. We find that the Vulcan timing measurement does not agree with the previous exponential decay model. This led us to re-evaluate the other… 
The hierarchical triple nature of the former red nova precursor candidate KIC 9832227
We revisit the issue of period variation of the recently claimed red nova precursor candidate KIC 9832227. By using the data gathered during the main mission of the Kepler satellite, and data
Period Changes of 14,127 Contact Eclipsing Binaries in the Galactic Bulge
We present the orbital-period variations of 14,127 contact eclipsing binaries (CEBs) based on the OGLE-III&IV observations in the Galactic bulge. New times of minimum lights for the CEBs were derived
Luminous red novae: Stellar mergers or giant eruptions?
We present extensive datasets for a class of intermediate-luminosity optical transients known as luminous red novae. They show double-peaked light curves, with an initial rapid luminosity rise to a

Binary and multiple stellar systems are numerous in our solar neighborhood with 80 per cent of the solar-type stars being members of systems with high order multiplicity. The Contact Binaries Towards
Runaway Coalescence of Pre-common-envelope Stellar Binaries
We study the process of runaway, unstable Roche lobe overflow in coalescing binary systems and its dependence on the properties of the binary involved. We create three-dimensional hydrodynamic models

We present Breakthrough Listen’s Exotica Catalog as the centerpiece of our efforts to expand the diversity of targets surveyed in the Search for Extraterrestrial Intelligence (SETI). As motivation,
Origin of the orbital period change in contact binary stars
The evolution of contact binary star systems in mass asymmetry (transfer) coordinate is considered. The orbital period changes are explained by an evolution in mass asymmetry towards the symmetry
From piz daint to the stars: simulation of stellar mergers using high-level abstractions
TLDR
