High Accuracy Radial Velocity Planet Searcher
Radial velocity measurements from High Accuracy Radial Velocity Planet Searcher with an amplitude of 4 km/s indicate that it is a spectroscopic binary of unknown period. The visible component is an A-type main-sequence star with a stellar classification of A0V, and has some slight abundance anomalies that resemble a weak Am star. It is catalogued as a shell star, showing spectral features of a cooler circumstellar jacket of gas, and may be a proto-shell star. The star is an estimated 254 million years old with a relatively low projected rotational velocity of 52 km/s. It has 2.67 times the mass of the Sun and is radiating 71 times the Sun's luminosity from its photosphere at an effective temperature of 10,507 K.
