High resolution observations of iota Herculis
- 1. Observatoire de Nice, B.P. 139, 06003 NICE CEDEX (France)
Description
Iota Her (B3 IV) has been known for a long time as a spectrum variable. Smith and Smith and Stern detected different periods in line profile variations and classified iota Her in their 53 Per group. Recently the Nice group and S. Gonzalez-Bedolla in Mexico observed it in photometry and spectrography at 12 A/mm. The main results are the detection of short period variations (0.12 or 0.14 day period) in photometry, radial velocity and on the He I 4387/Mg II 4481 lines intensity ratio. These short periodic variations are superimposed on longer ones which were first detected by Rogerson. The authors present here preliminary results of the 1985 campaign obtained with very high spectral resolution
