RX Gru is a pre-main-sequence eclipsing binary with twin components of mass ~1 solar mass each, age ~28 Myr, and a circumbinary companion of minimum mass 89 Mjup in a 23.8-year orbit.
The near-100% nitrogen enrichment of stars ≳100 M⊙ in 30 Doradus requires mixing far stronger than standard overshooting or winds, pointing to early interior mixing absent from current models.
Binary disruption and relaxation models explain the zone of avoidance and thermal eccentricities in S-star orbits around the Galactic center black hole.
New C, N, O, S, K, Cu abundances for 714 solar-neighbourhood stars show that ratios relative to oxygen discriminate thin- and thick-disk populations more clearly than traditional [X/Fe] trends.

Nitrogen rises to the top: evidence of enhanced mixing in very massive stars
The near-100% nitrogen enrichment of stars ≳100 M⊙ in 30 Doradus requires mixing far stronger than standard overshooting or winds, pointing to early interior mixing absent from current models.
