New Double Periodic Variable stars in the ASAS-SN Catalog

Mennickent, R. E.; Rosales, J. A.

We report the discovery of 3 new Double Periodic Variables based on the analysis of ASAS-SN light curves: GSD J11630570-510306, V593 Sco and TYC 6939-678-1. These systems have orbital periods between 10 and 20 days and long cycles between 300 and 600 days.

Confirmation of the magnetic nature of the delta Scuti star HD 21190

Hubrig, S.; Scholler, M.

HD 21190 is a known delta Scuti star showing Ap star characteristics and a variability period of 3.6h discovered by the Hipparcos mission. Our previous spectropolarimetric observations with FORS1 at the VLT showed the presence of a rather weak magnetic field of the order of a few tens of Gauss. New spectropolarimetric measurements with FORS2 at th…
