Massive B-type pulsators in low-metallicity environments
C. Karoff, T. Arentoft, L. Glowienka +5
Massive B type pulsators such as beta Cep and slowly pulsating B (SPB) stars pulsate due to layers of increased opacity caused by partial ionization. The increased opacity blocks t…

SPB stars in the open SMC cluster NGC 371
C. Karoff, T. Arentoft, L. Glowienka +5
Pulsation in beta Cep and SPB stars are driven by the kappa mechanism which depends critically on the metallicity. It has therefore been suggested that beta Cep and SPB stars shoul…
