On the evolutionary status of lambda Bootis stars using Hipparcos data
E. Paunzen
Using the Hipparcos data, absolute magnitudes and thus the evolutionary status for the group of lambda Bootis stars were derived. The origin of this small group of non-magnetic, ch…
Statistics on the spectral classification of CP2 stars in the Southern Sky
M. Rode, H. M. Maitzen, E. Paunzen
A number of about 1500 spectroscopically classified CP2 stars in the southern sky (delta =-90 to -12 degrees) was extracted from the Michigan Catalogue (Vols. I - IV). This sample…
The lambda Bootis stars
E. Paunzen
In this article the current knowledge of the group of lambda Bootis stars is reviewed. These metal poor objects are quite outstanding compared to other chemically peculiar stars of…
CP2 stars in clusters: deep Delta a-photometry
H. M. Maitzen, M. Rode, E. Paunzen
The search for chemically peculiar (CP) stars in open clusters using photoelectric photometry sampling the presence of the characteristic flux depression feature at 5200A via the D…
