Nablyudeniya, provedennye na 6-m teleskope s vysokim spektral'nym razresheniem v 2003–2011 gg., pozvolili detal'no izuchit' osobennosti opticheskogo spektra i polya skorostei v atmosfere polupravil'noi peremennoi LN Hya. Po slabym simmetrichnym fotosfernym absorbtsiyam naideny izmeneniya luchevoi skorosti ot daty k date (do 3 km/s), chto yavlyaetsya sledstviem slabykh pul'satsii. Obnaruzhena pekulyarnost' i peremennost' profilei sil'nykh linii Fe I, Fe II, Ba II, Si II i dr. Vyyavlena asimmetrichnaya forma profilei etikh linii: ikh korotkovolnovye kryl'ya vytyanuty, a yadra libo razdvoeny, libo iskazheny emissiei. V nablyudatel'nyi sezon 2010 g. ot spektra k spektru izmenyalis' polozhenie i glubina absorbtsionnogo komponenta H, intensivnost' korotkovolnovogo i dlinnovolnovogo emissionnykh komponentov, a takzhe otnoshenie ikh intensivnostei. V spektre 01.06.2010 g. poyavilis' slabye emissii neitral'nykh atomov (VI, MnI, CoI, NiI, FeI). Eti osobennosti spektra zvezdy, zaregistrirovannye vpervye, dayut osnovanie predpolagat', chto v 2010 g. udalos' zafiksirovat' bystroe izmenenie fizicheskikh uslovii v verkhnikh sloyakh atmosfery LN Hya.
