Oph-IRS 48 is a star surrounded by a protoplanetary disk, about 444 light-years from Earth in the constellation of Ophiuchus.

[3] The disk has changed the view of planet formation in astronomy.

Studies have shown that the millimeter dust particles are gathered in a crescent shape, while the gas (traced by CO molecules) and small dust grains follow a full disk ring structure.

[6] This structure is consistent with theoretical predictions of dust trapping.

[7] The dust trap is thought to be conducting the process of planet formation in this young system.
