5 Vulpeculae

This is a young A-type main-sequence star with a stellar classification of A0 V. It is a rapidly rotating star with a projected rotational velocity of 154 km/s. The star has an estimated 2.33 times the mass of the Sun and about 2.7 times the Sun's radius. It is radiating 34 times the Sun's luminosity from its photosphere at an effective temperature of 8,940 K.

A warm debris disk was detected by the Spitzer Space Telescope at a temperature of 206 K (−89 °F; −67 °C), orbiting 13 Astronomical units from the host star. Although this finding has not been directly detected, the emission signature indicates the disk is in the form of a thin ring. The emission displays weak transient absorption features that are indicative of kilometer-sized exocomets that are undergoing evaporation as they approach the host star. These absorption features have been observed to vary on time scales of hours, days, or months.
