Classification of the enigmatic Nantucket variable XX Sct.

BONJORNI J. and SAMUS N.

Abstract (from CDS):

The irregular variable XX Sct has been ascribed five different variability types since its discovery in 1924, from a Cepheid to a rapid irregular variable. Re-examination of nearly 1200 blue photographic plates of this star at the Maria Mitchell Observatory revealed strong irregular variability of up to 3 magnitudes on different time scales. Several possible periods have been found, none of which are particularly convincing. UBV photometry and a low-resolution optical spectrum are consistent with a reddened A star. We tentatively suggest that XX Sct is one of the class of young, intermediate mass Herbig Ae/Be stars known as UXors.
