The observation of Delta Sct and Gamma Dor stars by using MONS satellite

Description

The MONS space experiment will be able to verify some of the most important topics in the asteroseismologic studies of Delta Sct and Gamma Dor stars. We discuss how the $γ$ Doradus can be considered possible "bridges" between the opacity driven overstable pulsation and the stochastically excited solar like oscillation. For this reason the possible inclusion of a Gamma Dor representative in the MONS main target list is presented and discussed. To study Delta Sct stars, an appropriate frequency resolution, comparable to or better than what is currently achieved by ground-based observations, is necessary and hence two runs are recommended. To avoid over-scheduling of the Main Camera, a possible combination of observations from the Main Camera and from the Star Trackers is proposed. As a result, key-objects could be adequately monitored, affording the possibility to enter into details of amplitude variations. Simultaneously, the same results could be obtained on two Gamma Dor stars.
