Stellar Notes
RS 4.94 - 5.01V, 2.6131738d. Probable reflection effect.
2.6132d, K 9.5k/s, V0 +6.4k/s, asini 0.341. Eker and Doherty (1987, MNRAS, 228, 869) observed double lines at high | resolution and provide and alternate orbit. A primary temperature of 6750 K is estimated from Fe/C line ratio, while | equivalent widths of CaI and FeI lines from K-type secondary give 4500-5000 K. Implied spectral type of secondary is | K2IV.
