The star 2MASS J07363415+6538548 (hereafter 2M0736) was previously classified as a possible symbiotic binary, a cataclysmic variable, an H ii region, a massive star cluster, a supernova remnant, or a high-mass X-ray binary. In the previous research, while analyzing disputable symbiotic candidates in our New Online Database of Symbiotic Variables, we employed multi-frequency photometric observations, and reclassified the object as an active K-type dwarf. Here, we analyze the low-resolution spectroscopy of 2M0736 to confirm its photometric classification and validate that our methods are able to provide comparable results with the optical spectroscopy. The obtained spectrum confirmed that 2M0736 is a K6 dwarf. The presence and strength of the Hα emission line have verified that the object is very active.

先前将恒星2MASS J07363415 + 6538548（以下称为2M0736）分类为可能的共生双星，大地变星，H  ii区，大质量恒星团，超新星残留物或高质量X射线双星。在先前的研究中，在分析新的共生变量在线数据库中有争议的共生候选者的同时，我们采用了多频光度学观测，并将该对象重新分类为活跃的K型矮人。在这里，我们分析了2M0736的低分辨率光谱，以确认其光度分类，并验证了我们的方法能够提供与光学光谱相当的结果。所获得的光谱证实2M0736是K6矮星。为H的存在和强度α 发射线已验证对象非常活跃。
