Apsidal motion in the massive binary HD 152248
Abstract
The eccentric massive binary HD 152 248, hosting two very similar O7.5 III(f) stars, is the most emblematic eclipsing O-star binary in the very young and rich open cluster NGC 6231. Measuring the rate of apsidal motion in such a binary system gives insight into the internal structure and evolutionary state of the stars composing it.
