0 0 8 , ▁a ▁team ▁of ▁astronom ers ▁first ▁described ▁how ▁as ▁the ▁ex op lan et ▁orbit ing ▁HD ▁ 1 8 9 7 3 3 ▁A ▁reaches ▁a ▁certain ▁place ▁in ▁its ▁orbit , ▁it ▁causes ▁increased ▁stell ar ▁fl aring . ▁ ▁In ▁ 2 0 1 0 , ▁a ▁different ▁team ▁found ▁that ▁every ▁time ▁they ▁observe ▁the ▁ex op lan et ▁at ▁a ▁certain ▁position ▁in ▁its ▁orbit , ▁they ▁also ▁detected ▁X - ray ▁fl ares . ▁ ▁The oret ical ▁research ▁since ▁ 2 0 0 0 ▁suggested ▁that ▁an ▁ex op lan et ▁very ▁near ▁to ▁the ▁star ▁that ▁it ▁or bits ▁may ▁cause ▁increased ▁fl aring ▁due ▁to ▁the ▁interaction ▁of ▁their ▁magnetic ▁fields , ▁or ▁because ▁of ▁tid al ▁forces . ▁ ▁In ▁ 2 0 1 9 , ▁astronom ers ▁analyz ed ▁data ▁from ▁A reci bo ▁Observ atory , ▁M OST , ▁and ▁the ▁Autom ated ▁Ph oto elect ric ▁T eles cope , ▁in ▁addition ▁to ▁historical ▁observations ▁of ▁the ▁star ▁at ▁radio , ▁optical , ▁ult rav io let , ▁and ▁X - ray ▁w avel ength s ▁to ▁examine ▁these ▁claims . ▁ ▁They ▁found ▁that ▁the ▁previous ▁claims ▁were ▁ex agger ated ▁and ▁the ▁host ▁star ▁failed ▁to ▁display ▁many ▁of ▁the ▁bright ness ▁and ▁spectral ▁characteristics ▁associated ▁with ▁stell ar ▁fl aring ▁and ▁solar ▁active ▁regions , ▁including ▁sun sp ots . ▁ ▁Their ▁statistical ▁analysis ▁also ▁found ▁that ▁many ▁stell ar ▁fl ares ▁are
