This star was reported to have stellar activity, making the confirmation process for CoRoT-7b more difficult.

The stellar activity is limiting us to audio only, and even that isn't perfect.

Will, get to the bridge and monitor both the shield situation and stellar activity.

The second is that events on earth are also initiated through planetary and stellar activity.

The stellar activity is increasing at a much greater rate than I'd anticipated or than the computer had calculated on the basis of available data.

The few police forces that remain apparently spend more time investigating unusual stellar activity than actual crimes.

The flare was surprising because intense stellar activity is not expected around stars of such age.

She also worked with others on discoveries concerning stellar activity in distant galaxies.

However, this may be an artifact of stellar activity.

I gather the gamma rays also make for increased stellar activity.
