HR 5825 is an F-type main-sequence star in the constellation of Lupus.[1] It has an apparent visual magnitude of approximately 4.64.[1] A debris disk has been imaged around this star using the coronagraphic mode of the ACS instrument on the Hubble Space Telescope. The disk appears to have a dust maximum at 83 AU from the star and a sharp outer boundary at 109 AU. These features may be caused by gravitational perturbations from planets orbiting the star.[6]
