Abstract (from CDS):

DG Ari (ASAS J025521+1539.4) is a variable star that was found in the search of binary stars with periods longer than 30 days in ASAS catalogue. The source shows two periodic component in its light curve. We estimate both, the orbital period, and the long-term cycle using PDM. Additionally, we present a match with the soft X-ray source 1RXSJ025521.3+153951 located at similar position. According with these results, we discuss about its nature as a RS CVn candidate.
