TL;DR: S CrA N exhibits strong accretion and ejection phenomena. Spectropolarimetry provides complementary information to other techniques, allowing for a detailed view of the innermost regions of the star. However, the complex magnetic field topology is inconsistent with the observed magnetic signatures of the emission lines.

TL;DR: Researchers use near-infrared interferometry to study a quasar at z=4, resolving its broad-line region and detecting a prominent outflow with velocities up to 10^4 km/s, yielding a black hole mass of 8 M⊙.

TL;DR: In this article , the authors present an experiment set to address a standard specification aiming at avoiding local turbulence inside the Coudé train of telescopes, where every optical surface should be kept within a 1.5° range around ambient temperature.
The interplay between disk wind and magnetospheric accretion mechanisms in the innermost environment of RU Lup
