Abstract—Based on archived images from the Hubble Space Telescope, stellar photometry of the dwarf galaxy Coma P, located near the Virgo galaxy cluster, was performed. The selection of weakly luminous regions of the galaxy showed that Coma P consists of two interacting dwarf galaxies, one of which has a weak star formation, and the second galaxy has a very low surface brightness, there is no star formation in it, and it can be called a “dark” galaxy. The distance to this pair of galaxies, measured by the TRGB method (D = 12.7 ± 0.9 Mpc), showed that Coma P is located on the periphery of the Virgo galaxy cluster.

处女星系星团外围的“半暗”矮星系彗星P

摘要—基于哈勃太空望远镜的存档图像，对位于处女座星系团附近的矮星系昏迷彗星P进行了恒星测光。对银河系微弱发光区域的选择表明，彗星P由两个相互作用的矮星系组成，其中一个星系形成较弱，第二个星系的表面亮度很低，没有星系形成，并且可以称为“黑暗”星系。到这对星系的距离，由TRGB方法（测量d = 12 。 7±0 。 9 MPC），表明昏迷P被位于处女星系簇的外围。
