| 英文摘要 | Abstract We report the identification of the optical counterpart to the companion of the millisecond pulsar J2317+1439. At the timing position of the pulsar, we find an object with , , and . The magnitudes and colors of the object are consistent with a white dwarf (WD). Compared with WD cooling models, we estimate that it has a mass of , an effective temperature of K, and a cooling age of 10.9?±?0.3 Gyr. Combining our results with published constraints on the orbital parameters obtained through pulsar timing, we estimate the pulsar mass to be . Although the constraint on the pulsar mass is still weak, there is a significant possibility that the pulsar could be more massive than two solar masses. |
