In order to classify the charmed-strange mesons, including puzzling D{sub s0}*(2317) and D{sub s1}(2460), and recently observed D{sub s1}*(2710) ans D{sub sj}*(2860), we employ the U-tilde(12)xO(3,1) level-classification scheme of hadrons proposed and developed by us in recent years. The scheme has a new degree of freedom, SU(2){sub {rho}}, which leads to a number of extra states out of conventional SU(6)-scheme, named chiralons. Applying this novel classification scheme, we investigate the strong decays of S- and P-wave cs-bar mesons with one pseudoscalar emission by using the covariant oscillator quark model. As a result it is shown that D{sub s0}*(2317) and D{sub s1}(2460) are described as {sup 1}S{sub 0}{sup {chi}}and {sup 3}S{sub 1}{sup {chi}}chiralons, forming the SU(2){sub {rho}}doublet with the ground-state D{sub s} and D{sub s}*, respectively. Furthermore, the observed decay properties of D{sub s1}*(2710) is consistently explained as the vector chiralon {sup 1}P{sub 1}{sup {chi}}. On the other hand, it is also found that the controversial narrow state, D{sub sj}*(2860), does not fit as predicted properties of our P-wave vector chiralon.
