AW Mic: The RR Lyrae That Wasn’t

Abstract

AW Mic is a neglected star that has previously been categorised as an ‘unusual’ RRc variable. This paper makes use of new and archival observations of AW Mic to establish that this star is no longer varying in magnitude and should no longer be classified as an RR Lyrae variable. Mid magnitudes of 9.171 ± 0.026 and 9.001 ± 0.014 are reported for this star in the B- and V-bands, respectively.
