(HD 62623)

It appeared in the literature as the first A[e]SG [49,176] and is known to be surrounded by a detached gas and dust disk, from which also CO band emission has been detected [39,58]. It has been speculated that the gap between the star and the inner rim of the gas disk might have been cleared by a companion. However, no clear evidence of such a companion has been found yet. Its low luminosity and large errors in the near-IR photometric measurements make it challenging to unambiguously assign the star a B[e]SG status, although its position within the near-IR seems to coincide more with the B[e]SG domain rather than with any other classification. This object is an ideal candidate to clarify its nature based on dedicated K-band observations to analyze the 13CO content within its circumstellar disk.
