Surrounded by the sun's famous star's sun

Out of the light of the six light, Barnard's star attracted exooplanet hunters from the 1960s. The only closest single star in the Sun is to the Alpha and the Century Triple Star system.

Barnard's star is among the closest red dwarfs to seek future solar system probes that future Interstellar spacecraft can reach. Professor Evertertus co-writer Steven Vogt, astronomer and astronomy at the UC Santa Cruz, said, "Evidence of the planets around this famous red dwarf star has failed in the last 50 years.

Messages from high-precision instruments, including High-Resolution Ake Spectrometer (HIRES) in Hawaii, Barnard's star star (or GJ 699b) at least 3.23 Earth masses orbit every 233 days a red dwarf star. This will place the planet in the area called the ice sheets of the star, where it will be a frozen world.

Results of the group will appear online. November 14, 2018 Issue Magazine Nature.

Because of the atmosphere, the planet's temperature is -150ºC. It is unlikely to support liquid water on the surface. However, it is aimed at direct imaging using the tools of the next generation.

"This finding is a stimulus to continue searching solar energy solar systems around our neighbor next to our neighbors," said Interstate-based researcher Cristina Rodríguez-López, "that's what we hope to live in hospitality." Astrophysia D Anthology (IAA, CSIC).

Barnard's star moves into the night sky faster than any other star. It is one of the oldest red dwarfs that is older than our sun. "The 70% of the galaxy is the most common star in the Milky Way galaxy, and this is a smooth star," said Vaught. "Although it is very close, Barnard's star can not be seen with the naked eye."


Vogt's Exoplanet Search Team In 1997, & # 39; & # 39; s Kear Observatory. Hirish & # 39; Bernerard observed the star using the device. The microscopic telescopes of an object whose gravitational tube is derived from an orbit, and used the radial speed method to measure lateral movements.

However, signals that identify Earth-size planets are just behind their host star and fall in large quantities by the sound created from the brilliant surface activity of the stars.

"We knew we were going to be patient, and we followed Barnard's star for 16 years, along with 260 radial velocities of 2013 by Bern Barnard's star," Vogt said. "Our Long-Term Planet Program has begun to understand the time required to gather enough precision radial speed data, a planet."

In 2016 Vog's European colleague Micho Tumi delivered the team's hirosse data from the UVS and Harps spectrometers of the European Southern Observatory. Even though the radial tilt is about 230 days in data, the size of the planet.

But at that time astronomers viewed it seriously and published their findings. The UCL liquevere added 45 more radial speeds to the newly commissioned automated Planet Finder (APF) telescope. Cassigi Institute for Science Planet Finder Spectrograph (PFS) 39 misses at Chagalli Observatory at Magellan II Telescope in Las Casas, and in recent years more accessible from HARPS. In each case, the more information about the 230-day signal creates more powerful and more relevant.

The rebel group decided to launch an intensive surveillance campaign from 2016 to 2017, after the planet was discovered by the planet using spectrograph cameras, whose life was shot in Spain's Karl-Olto Observatory.

"More information from Carmen confirmed these signals regularly and removed any suspicions about the planet's reality," said Vaught.

"For analyzing, we have used observations from seven different devices, one of the largest and most extensive databases used in accurate radial speed studies, which is based on 20 years of rest, a total of 771 measurements have been combined," Ribas said.

Within 233 days a clear signal was added again. This signal indicates that Barnard's star becomes closer to us from 1.2 meters per second-an easy walk away from the behavior of an individual – this movement is described as a result of a star-starred planet.

"After very careful analysis, we believe that 99 percent of people have planet on the planet, as this is a model for our observation," Ribas said. "However, we need to be careful to collect more information on the case in the future, because the natural effects of stars resulting from star crystallis can generate similar results."

Next steps

The closure of Barnard's star is already done in different observatories. Vogt's findings suggest that Jupiter's size could be influenced by the size of Jupiter. However, there are more planets than the Earth's orbits.

Before the use of radial fast technology, a few telescopes have not been very far from their orbital origin. This means that astronomers are better off finding solar planets outside our solar system.

"We're all very hard on this outcome," said Guy-member Angela-Sqoodi, co-leader of Queen Mary University in London. "This is the result of a large collaboration organized in the context of Red Dots Project, which is why donations from around the world are organized by semi-professional astronomers coordinated by the American World Association of Variable Star Observers."

Exoplanet statistics confirm that there are more planets in the universe than the stars we have discovered, and the beaches of our planet with sand than the grains! "Vote said," The Super Earth is very cathartic.
