HD 95086 is a pre-main-sequence star about Шаблон:Convert away. Its surface temperature is 7,750Шаблон:± K. HD 95086 is somewhat metal-deficient in comparison to the Sun, with a metallicity Fe/H index of −0.25Шаблон:± (~55%), and is much younger at an age of 13.3 million years. It was originally thought to be part of the Lower Centaurus-Crux association, until it was found using Gaia data that the star may be instead part of the Carina association.

Multiplicity surveys did not detect any stellar companions to HD 95086 as of 2013.

Nomenclature

The designation HD 95086 comes from the Henry Draper Catalogue.

In August 2022, this planetary system was included among 20 systems to be named by the third NameExoWorlds project. The approved names, proposed by a team from Greece, were announced in June 2023. HD 95086 is named Aiolos after a Greek mythological figure, and its planet is named Levantes, from a modern Greek word referring to easterly Mediterranean winds.

Planetary system

In 2013, one planet, named HD 95086 b, was discovered on a wide orbit by direct imaging. The discovery was confirmed in 2014.

Besides the planet, the star is surrounded by a complex, relatively massive (0.5Шаблон:± Шаблон:Earth mass) debris disk, which may consist of up to four belts (Hot, Warm, Cold and Halo) separated by gaps. A small amount (1.4–13)×10⁻⁶ Шаблон:Earth mass of gaseous carbon monoxide was detected in the outer disk, implying a recent collisional cascade followed by cometary activity of fresh debris.
