Our planet can be perceived as an object of middle age. Its figure of 4.5 billion years seems huge, but compared to the age of the Universe (13.8 billion years), it only approaches the stage of maturity. However, outside the solar system you can literally find babies who are just beginning their life.
Today, we turn our attention to the territory of the Taurus constellation, where, at a distance of 427 light years, the young star rotates with the exoplanet V830 Taurus b. We can say that we have a record holder, because with an indicator of 2 million years, this world is considered the youngest among the known planets.
Here is an exoplanet of the type hot jupiter, distant from its native star by 0.057 a. e., which is 7 times less than the distance of the Mercury-Sun. By mass, it reaches 77% of the Jupiter index. The temperature of its star is 4250 K, so that because of its proximity, the world receives a lot of heat and dangerous radiation.
Parental star is type T Taurus. That is, it is an evolutionary stage when the star is only to enter the main sequence. Usually, a protoplanetary disk in such stars is delayed by 10 million years, after which it is scattered. Perhaps there is another exoplanet nearby. Researchers believe that the V830 Taurus b continues to face the circumstellar material, so the planet is restless.
The age of this exoplanet is not only surprising, but also serves as an important indicator for scientists. Previously, the first place on the “youth” among the planets was occupied by K2-33 b (5-10 million years) and CVSO 30 b (about 10 million years).
The discovery of these planets allows you to confirm that hot Jupiters are likely to appear due to the contact of the planet and the star disk. In addition, these exoplanets are located close to the native stars, which means that the process of their migration to a greater distance covers several million years and begins later.
