TL;DR: In this article, the smallest intrinsic dispersions of σ ≤ 1% in θ LD are obtained for the surface brightness relations of these stars using exclusively direct angular diameter measurements.

TL;DR: In this article, the smallest intrinsic dispersions of sigma < 1% on theta_LD are obtained for the relations based on the K and L magnitudes, for instance log theta-LD = 0.5170 - 0.2 L or log thea-LD= 0.0755 - 0.2 K. The results are valid between the spectral types A0 and M2 for dwarf stars (with a possible extension to later types when using the effective temperature).

TL;DR: The first observations of a rapidly rotating Be star, Eridani, using Earth-rotation synthesis on the Very Large Telescope (VLT) Interferometer are reported in this article.

TL;DR: In this article, the authors fitted the RV variations of TW Hydrae using a cool spot model and showed that a cold spot covering 7% of the stellar surface and located at a latitude of 54 deg can reproduce the reported RV variations.

TL;DR: In this paper, the authors investigate the close neighbourhood of Vega with the help of infrared stellar interferometry and estimate the integrated K-band flux originating from the central 8 AU of the debris disk.
