Infrared spectroscopy of symbiotic stars. XI.

Employing new infrared radial velocities, we have computed spectroscopic orbits of the cool giants in four southern S-type symbiotic systems. The orbits for two of the systems,...本研究借助新获取的红外视向速度（infrared radial velocities）数据，为4个南天S型共生星系统（southern S-type symbiotic systems）中的低温巨星（cool giants）求解了光谱轨道（spectroscopic orbits）。其中两个系统的轨道……
