Abstract

We revisited the BeppoSAX observation of SAX J0635+0533, which was suggested as a possible counterpart to the gamma-ray source 2EG J0635+0521. We have discovered a 33.8 ms pulsation from the source and derived an improved position, consistent with the location of the Be star proposed as a binary companion. We interpret the periodicity as the spin period of a neutron star in a binary system with a Be companion.

摘要

我们重新审视了对SAX J0635+0533的贝波萨克斯观测，该天体被认为可能是伽马射线源2EG J0635+0521的对应体。我们发现该源存在33.8毫秒的脉动，并得出了一个更精确的位置，这与被提议作为双星伴星的Be星的位置相符。我们将这种周期性解释为一个具有Be伴星的双星系统中中子星的自转周期。
