Uncertain classification and identification. Triple system. tet 1 Eri is a spectroscopic binary (2001A&A...376..586F) and it has been chosen as the variable star with potential ELL variations in an moderately eccentric orbit. tet 2 Eri (V= 4.35, A1VpMg) is 8.4" away. Combined mean magnitude V= 2.90 with amplitude 0.016. tet 2 Eri might be the actual variable, showing ACV variations. In that case, the corrected amplitude would be 0.06 mag. |
