| 摘要 | G328 = A65 = L3314 (V = 13.83, B - V = 1.91) is a field star in the direction of the globular cluster M4. If we take E(B - V) 0.40, then its (B - V)(0) = 1.51, corresponding to a spectral type of K5III if it is a giant star; or of dM2 if it is a dwarf. Observations at both the MSSSO and Yunnan Observatory have shown that G328 is a new variable with peak to peak amplitude similar or equal to 0.05 mag in V. While it is not unusual for so red a star to be a variable, special attention must be paid to its short period of about one day. If the variability is due to pulsation, the spectral type and luminosity as well as effective temperature should be determined in order to compare it with Xiong's theory. |
