Stellar Notes

SX Ari 5.67 - 5.81V, 0.7278925d. Spectral variations (SiII, HeI, same period). Possible 30 min Sp. var. | suggesting star spots related to magnetic field. Silicon abundance varies 10 to 100 times solar, and magnesium 0.03 to | 10 times solar.
Period 0.728d probably rotation period. Earlier determination vsini 94k/s.
