The p.ssibility of the life origin.in.the stellar systems, located at a distan.e of ~200 p. from the solar system, was in.estigated. The stars, in.the sp.ctrums of which C (carbon., O (oxygen., n.(n.trogen., an. p.(p.osp.orus) are foun., are called Dn.-stars. Based on.stellar abun.an.es a n.w method for searchin. for habitable exop.an.ts has been.develop.d an. a list of 48 Dn.-stars in.the solar n.ighborhood, on.which life is p.ssible, has been.defin.d. The quota of Dn.-stars is equal 1.3% of the total amoun. of Hyp.tia Stellar Catalog. On.y three Dn.-stars out of selected 48 stars belon. to the sp.ctral class as our Sun.(G2V). The closest to the solar system is the Dn.-star with the n.mber HIp.15510, which belon.s to the G8V class an. is 6 p. away from the solar system. n.n. Dn.-stars, which have the highest chemical similarity with solar sp.ctrum, were iden.ified. It is iden.ified that on. of these n.n. stars, HIp.24681, has six p.an.ts.
