In the past weeks and months, there have been several reports about intense solar flares as the sun approaches its solar maximum. However, according to a report, it's not as active as the members of the binary star system V1355 Orionis.
Solar Flare From Sun Not as Intense as Superflares From V1355 Orionis' Star
Periodically, a star in the constellation V1355 Orionis emits superflares. These eclipse the largest solar flare ever observed on the Sun by a factor of ten.
Solar flares frequently cause geomagnetic storms on Earth (known as "space weather"). In the worst circumstances, severe storms can obstruct our technological advancements. They can harm satellites, stop electrical grids, and interfere with communications, ScienceAlert reported.
Flares that are intense, like the ones at V1355 Orionis, may have much more detrimental impacts. It can affect planetary atmospheres and the evolution of any nearby planets. Such flares could exterminate all life on those planets if they are powerful enough. It is crucial to comprehend stellar flares and their causes.
The star's escape velocity of 347 km/sec was far exceeded by the eruption's velocity, which was at least 990 km (615 miles) per second. A coronal mass ejection formed as it evolved, launching trillions of tons of matter into space.
According to Universe Today, we should be thankful that our sun doesn't emit flares like that.
In a previous report from Science Times, an X-class solar flare hit Earth, and it caused a radio blackout for about an hour in some parts of Southeast Asia, Australia, and New Zealand. "X" flares are considered the strongest and biggest flares, but the one that hit the Earth wasn't the largest as it was only X1.2. Sun can produce flares as big as X28.
Understanding V1355 Orionis' Superflares
The V1355 Orionis is categorized as an RS CVn star. The RS Canum Venaticorum system contains close binary stars. V1355 Orionis is 400 light-years away in the constellation Orion, SpaceRef reported.
Large superflares frequently erupt from the surfaces of these magnetically active stars. They frequently feature huge starspots as well.
These systems are divided into subgroups, including flare stars like V1355 Orionis. In radio frequencies and X-rays, some are quite bright.
Both a K- and G-type star can be found in V1355 Orionis.
A subgiant, the K star is the origin of the superflare. These studies' findings highlight the need for additional modeling and simulation of prominences on this type of star, particularly in a binary system.
It's critical to understand better the mass that the star loses due to its prominences and related coronal mass ejections.
To comprehend prominences and flares on our Sun and how they occur there, it is helpful to study the superflare V13555 Orionis. Additional observations should clarify what is happening on both types of stars' surfaces and with their magnetic fields.
The team's measurements are intended to aid astronomers in their understanding of how superflares and eruptions start.
