At AOP we run a program of weekly seminars, except during the summer.
Our Seminars are being held in hybrid mode, with everyone on-site in Armagh very welcome to meet in the Library for the Seminar where it will be shown on the large display Screen. Many of our speakers this seminar will be in Armagh in person.

The Effect of Tidal Interactions on Hot Subdwarf B Stars and Their Pulsations.Abstract:
Hot subdwarf B stars are evolved core He-burning stars formed by binary interactions with a nearby stellar companion. Many sdBs reside in close binaries which experience strong tides yet the systems are most likely not tidally synchronized. These stars have been both predicted and observed to pulsate with multiple frequencies. Asteroseismological analysis of the observed pulsations shows that they do not quite fit with the theoretical models, especially in the close binary systems. The tidal interactions effect the expected frequencies of pulsation in these stars.
