Enhanced H<sub><i>α</i></sub>activity at periastron in the young and massive spectroscopic binary HD 200775
Young close binaries clear central cavities in their surrounding circumbinary disk from which the stars can still accrete material. This process takes place within the very first astronomical units, and is still not well constrained as the observational evidence has been gathered, until now, only by means of spectroscopy. The …
