YSO 244-440 (also nicknamed the Stellar Sprinkler) is a binary system of young stellar object s (YSO) located 1,300 light years from Earth in the constellation of Orion. The two objects have an orbital separation of 30-40 AU. The larger object has a mass of about 0.5 solar masses while the smaller object orbiting it has a mass of around <0.2 solar masses. It has an age of roughly 0.1-0.2 million years old. It is a giant proplyd with a radius of approximately 1,400 AU across making it one of the largest proplyds in the Orion Nebula Cluster (ONC). [2] [3]
The system has a bipolar jet with a noticeable S-shape morphology. The morphology of the jets is from the material being launched from the smaller star orbiting the larger. [2] Another factor in the shape of the bipolar jet is the strong amounts of radiation produced by the stars. [4]
