Denebola

Denebola, designated Beta Leonis, is the second-brightest star in the zodiac constellation Leo and lies at the tip of the lion’s tail. The name Denebola comes from Arabic, meaning "tail of the lion." It is an A-type main-sequence star (spectral type A3V) with a white hue and an apparent magnitude of about 2.1. Based on parallax measurements, it is located at a distance of roughly 36 light-years from the Sun (about 11 parsecs).

Denebola is relatively young compared with the Sun, with an estimated age of several hundred million years. It rotates rapidly, a common trait among A-type stars, and has a higher surface temperature than the Sun.

The star hosts a circumstellar debris disk, detected as infrared excess and subsequently imaged at submillimeter wavelengths. The disk consists of dust in a belt at tens of astronomical units from the star, indicating the presence of planetesimal material and potential dynamical shaping. As of current knowledge, no exoplanet has been confirmed around Denebola.

In summary, Denebola is a nearby, bright, young A-type star notable for its surrounding debris disk as well as its position as the tail-end beacon of Leo.
