Sentences with phrase «flare activity»

The Sun goes through cycles of solar flare activity about every 11 years.

Thus we have three stars and possible planets at markedly different stages of development, giving us the ability to take a deeper look into flare activity on M - dwarfs as they age, and to assess flare effects on planetary habitability, assuming Barnard's Star and Ross 154 do have planets.

We'd like to know how stars like this age, considering that young M - dwarfs can show strong flare activity.

Because Proxima Centauri is known for flare activity, not to mention 400 times the X-ray flux the Earth receives.

In the 1970s and 1980s, some astronomers suggested that observed flare activity or light minima in EV Lac's light curve between flares could have been caused by an eclipsing companion with an orbital period of around 45 years and a high orbital eccentricity (e ~ 0.5)(G. Sh.

Flare activity fluctuates in a 11 - year cycle, which is currently ramping up.

Analyzing measurements of high - altitude airglow gathered by a satellite in 1992 and 1996 (years of maximum and minimum solar flare activity, respectively), the scientists found 11 cases where airglow, in theory, brightened enough to be seen by observers on the ground, they report in Geophysical Research Letters.

The Solar Physics group at Northumbria University is advertising a fully - funded PhD studentship on «The evolution of solar active regions and its relation to flaring activity».

These spots show little, if any, flare activity and what looks to be occurring is a reduction in F10.7 and EUV output when the Negative Spots dominate.

The theory suggests that during times of low solar output the reduced solar wind allows more cosmic rays to excite the outer atmosphere which then enhance any solar flare activity to a state whereby aurora can be visible at mid latitudes.
