The Mg I b triplet and the 4571 Å line as diagnostics of stellar chromospheric activity
C. Sasso, V. Andretta, L. Terranegra +1
Context. The Mg I 4571 Å line and the b triplet are denoted in the literature as diagnostics of solar and stellar activity since their formation is in the low chromosphere. Aims. T…
Discovery of Scuti pulsation in the Herbig Ae star VV Ser
V. Ripepi, S. Bernabei, M. Marconi +7
A new observational study of the Herbig Ae star VV Ser has been performed in order to detect and accurately measure pulsation frequencies in the Scuti range. As it belongs to t…
A multisite photometric campaign on the Pre-Main-Sequence delta Scuti pulsator IP Per
V. Ripepi, S. Bernabei, M. Marconi +18
We present the results of a photometric multisite campaign on the Scuti Pre-Main-Sequence star IP Per. Nine telescopes have been involved in the observations, with a total of a…
The GSC-II-based survey of ancient cool white dwarfs I. The sample of spectroscopically confirmed WDs
D. Carollo, B. Bucciarelli, S. T. Hodgkin +6
The GSC-II white dwarf survey was designed to identify faint and high proper motion objects, which we used to define a new and independent sample of cool white dwarfs. With this su…
Multisite observations of the PMS delta Scuti star V351 Ori
V. Ripepi, M. Marconi, S. Bernabei +12
We present the results of multisite observations spanning two years on the pre--main-sequence (PMS) star V351 Ori. A total of around 180 hours of observations over 29 nights have b…
Detection of delta Scuti-like pulsation in H254, a pre-main sequence F-type star in IC 348
V. Ripepi, F. Palla, M. Marconi +4
We present time series observations of intermediate mass PMS stars belonging to the young star cluster IC 348. The new data reveal that a young member of the cluster, H254, undergo…
