Low-luminosity Wolf-Rayet stars: a model-data comparison
Siyu Wu, Zhi Li, Yan Li
A growing number of Galactic Wolf-Rayet (WR) stars, in particular WC and transitional WN/C (WNC) objects, have been reported at comparatively low luminosities. If confirmed, these…

The transport of angular momentum for massive stars I. Formation of slowly rotating WNE stars
Jijuan Si, Yan Li, Xue-Feng Li +1
The evolutionary scenario of early-type nitrogen-sequence Wolf-Rayet (WNE) stars predicts a slowly rotating subclass that typically forms after the red supergiant (RSG) phase. Thei…

Formation of WNL stars for the MW and LMC based on the k-omega model
Jijuan Si, Zhi Li, Yan Li
We adopt a set of second-order differential equations ( model) to handle core convective overshooting in massive stars, simulate the evolution of WNL stars with different met…
