The extrasolar planet DP Leonis b orbits the 17th magnitude star DP Leonis in the constellation Leo. It is a gas giant exoplanet in the habitable zone of a B-type star. This 6.28 MJ planet orbits two stars, a white dwarf and a red dwarf, at a distance of around 8.6 AU and with an unknown eccentricity. It was discovered in 2009, and its finding was announced.
DP Leo b is an exoplanet that orbits the star DP Leo, which is 1304.6 light-years (400.0 pc) from our Solar System. It has a mass of 6.28 Jupiters, takes 28 years to complete one orbit around its star, and is 8.19 AU away from it. The apparent magnitude of the host star, DP Leo, is 17.5, with an absolute magnitude of 9.5.
DP Leonis is an A-lister. It is not part of the Leo constellation shape, but it is within its boundaries. The DP Leonis color is blue-white based on the star’s spectral type (AM Her). The star cannot be seen with the naked eye and must be viewed with a telescope. DP Leonis’s color and type are blue-white based on the spectral type of AM Her.
It is 0.7 times more massive and 0.6 times larger than our Sun. The surface temperature is 3500 degrees Fahrenheit, and the spectral types are AM Her. Planets orbiting post-common envelope binaries provide crucial information on planet creation and evolution, particularly for the relatively unknown type of circumbinary planets. The extrasolar planet DP Leo b orbits the star DP Leo every 10230.0 days at an orbital distance of 8.19 AU in this planetary system.
Many eclipsing post-common envelope (CE) binaries, notably the catastrophic variables, exhibit long-term eclipse-time variations, which represent either genuine or apparent orbital period alterations. The apparent magnitude of DP Leonis is 17.50, which is a measure of the star’s brightness as seen from Earth. Visual Magnitude is another name for Apparent Magnitude. Absolute Magnitude is the apparent magnitude of a star as seen from a distance of 10 parsecs (32.6 light years). This presupposes that there are no obstacles between the object and the observer, such as dust clouds.
