TL;DR: In this article, the authors constructed a model of the inner regions of the binary and proposed that these dips could be caused by partial occultation of the central binary by the accretion stream onto the primary star.

TL;DR: In this paper, the authors presented an analysis of a slightly eccentric (e = 0.05), partially eclipsing, long-period (P = 69.73 days) main-sequence binary system (WOCS 12009, Sanders 1247) in the benchmark old open cluster M67.

TL;DR: In this paper, the authors applied a maximum-entropy spot model to the long-cadence out-of-transit photometry of the target to derive maps of the starspot filling factor versus the longitude and the time.

TL;DR: Recently, a growing body of evidence for magnetic star-planet interactions includes a diverse array of photometric, spectroscopic and spectropolarimetric studies as discussed by the authors, the nature of which is modeled to be strongly affected by both the stellar and planetary magnetic fields, possibly influencing the magnetic activity of both bodies, as well as affecting irradiation and nonthermal and dynamical processes.

TL;DR: In this paper, the authors used a MCMC approach to estimate the orbital parameters and dynamical mass of the brown dwarf from those data, which is compatible with the available astrometric data of the star, as well as with the VLT/SPHERE and VLT-NaCo nondetection.
