Stars are preferably formed in large molecular clouds due to gravitational collapse. Serpens South is a unique star cluster with a very high protostellar fraction, indicating that it is a very young region with active star formation. Within the region, many protostars are providing important mechanical feedback via outflows, and we particularly investigated the molecular outflow driven from the Class 0 protostar known as CARMA-7. Atacama Large Millimeter Array (ALMA) observations with 1 arcsecond resolution uncovered a well-collimated, episodic outflow with distinct ejecta knots. This outflow, traced with carbon monoxide (12CO), appears to be mostly blueshifted to the south and redshifted to the north, with radial velocities up to at least 22 km/s. We will present the first proper motion study of this outflow by comparing observations taken in 2015 and 2019, in order to determine the inclination angle and speed of the outflow. As a result, this analysis will constrain the timescales and power of the outflow, which are important for regulating the star formation processes in the earliest stages where the conditions are set for planet formation.

Role: I am a bridge to Doctorate student in Astronomy in the University of Virginia. My research is to detect proper motion of CARMA7 in Serpens South star cluster. My advisor took observations and I am handing all the dataset in order to detect proper motion/inclination angle of the CARMA7.
