    • Magnetic massive stars as progenitors of 'heavy' stellar-mass black holes 

      Petit, Véronique; Keszthelyi, Zsolt; MacInnis, R.; Cohen, David H.; Townsend, R.H.D.; Wade, Gregg A.; Thomas, S.L.; Owocki, Stanley P.; Puls, Joachim; Ud-Doula, Asif (2016-12-02)
      The groundbreaking detection of gravitational waves produced by the inspiralling and coalescence of the black hole (BH) binary GW150914 confirms the existence of 'heavy' stellar-mass BHs with masses > 25 M⊙. Initial ...

    • X-ray emission from magnetic massive stars 

      Nazé, Yaël; Petit, Véronique; Rinbrand, Melanie; Cohen, David H.; Owocki, Stanley P.; Ud-Doula, Asif; Wade, Gregg A. (2014-10-30)
      Magnetically confined winds of early-type stars are expected to be sources of bright and hard X-rays. To clarify the systematics of the observed X-ray properties, we have analyzed a large series of Chandra and XMM-Newton ...
