The O-C diagram of the subdwarf B pulsating star HS2201+2610: detection of a giant planet?
R. Silvotti, S. Schuh, R. Janulis +9
In this article we present the O-C diagram of the hot subdwarf B pulsating star HS2201+2610 after seven years of observations. A secular increase of the main pulsation period, Pdot…
