M55Ve

M55Ve is a designation that has appeared in some informal discussions as a hypothetical variable star located within Messier 55 (NGC 6809), a globular cluster in the constellation Sagittarius. In widely used catalogs and literature, there is no confirmed object by the exact name M55Ve, and the designation is not part of the standard naming schemes for Messier 55 members. The term may reflect a misprint, a shorthand used in non-peer-reviewed notes, or a fictional or speculative entry used for teaching or thought experiments.

If such a star were real, it would lie at the distance of M55, embedded in a dense stellar field. Globular cluster variables are commonly RR Lyrae or SX Phoenicis types; an emission-related suffix could suggest spectral features observed in emission, though emission-line variables are not typical for these classes in globular clusters. No time-series photometry or spectroscopy specific to M55Ve has been published, and no measured period, amplitude, or spectral classification is publicly documented.

Status: At present, M55Ve remains unconfirmed in major astronomical resources. The designation serves as a reminder of the need to verify object names against established catalogs, such as SIMBAD or VizieR, to avoid confusion with known cluster members labeled with standard variable-star designations within M55.
