Stellar Notes
Alpha CV 5.22 - 5.27V, 5.0035d.
Triple SB system. Combined mag., colors.
6.3933d, K 67.4k/s, V0 +24.5k/s, asini 5.88. 5.8 - 7.8v, sep. 0.0003" and 6.0, sep. 0.3".
Spectrum shows phosphorus. Magnesium deficient relative to oxygen. Gallium II lines strong. Normal SiII, weak MgII. | Lambda Boo type. HgMn star. It has been suggested that a nearby supernova explosion could have produced reactions | to account for abundance anomalies.
