特性 编辑

金牛座DH是一顆M型或紅矮星恆星,是銀河系中最常見的恆星類型之一[6]。它的視星等只有13.71,因此從地球不能以裸眼直接看見,它的表面溫度為3,751 K。金牛座DH的質量為0.41 M,和估計它的半徑為1.26 R

它的伴星金牛座DH B或金牛座DH b的質量估計在8 MJ22 MJ之間,因此可能是顆超級木星棕矮星[7]。其它來源給出的質量高達0.03 M熱光度為0.01 L[8]。光譜類型被歸類為M7.5[8]或M9.25[9]。雖然主星仍然有一個原行星盤,且仍在吸積物質,但伴星被一個星周盤(可能是環行星盤英语Circumplanetary disk,須取決於它的形成歷史)包圍[10]
