This star is called HD73619 in Praesepe (M44) and is located in the Cancer constellation.

A group of Indian and international scientists have spotted a peculiar binary star that shows heartbeat but no pulsations, contrary to the norm of binary stars sporting both heartbeats as well as pulsations. This star is called HD73619 in Praesepe (M44), located in the Cancer constellation, one of the closest open star clusters to the Earth. A total of about 180 heartbeat stars are known to date. The name 'Heartbeat' stems from the resemblance of the path of the star to an electrocardiogram of the human heart. These are the binary star systems where each star travels in a highly elliptical orbit around the common centre of mass, and the distance between the two stars varies drastically as they orbit each other.
