The CoRoT star 105288363: strong cycle-to-cycle changes of the Blazhko modulation
Poretti, E.; Szabó, R.; Kolenberg, K. +4 more
We present an analysis of the COnvection, ROtation and planetary Transits (CoRoT) star 105288363, a new Blazhko RR Lyrae star of type RRab (f0= 1.7623 d-1), observed with the CoRoT spacecraft during the second long run in the direction of the Galactic Centre (LRc02, time-base 145 d). The CoRoT data are characterized by an exc…
CoRoT 102699796, the first metal-poor Herbig Ae pulsator: a hybrid δ Sct-γ Dor variable?
Catala, C.; Ventura, P.; Ripepi, V. +7 more
We present the analysis of the time series observations of CoRoT 102699796 obtained by the Convection, Rotation and planetary Transits (CoRoT) satellite that show the presence of five independent oscillation frequencies in the range 3.6-5 c d-1. Using spectra acquired with FLAMES@VLT, we derive the following stellar parameters: spectral…
