Vacuum and thermal properties of pseudoscalar and vector charm mesons are analyzed within a self-consistent many-body approach, employing a chiral effective field theory that incorporates heavy-quark spin symmetry. Upon unitarization of the vacuum interaction amplitudes for the scattering of charm mesons off light mesons in a fully coupled-channel basis, new dynamically generated states are searched. The imaginary-time formalism is employed to extend the calculation to finite temperatures up to T=150MeV. Medium-modified spectral shapes of the D, D*, Ds, and D*s mesons are provided. The temperature dependence of the masses and decay widths of the nonstrange D*0(2300) and D*1(2430) mesons, both showing a double-pole structure in the complex-energy plane, is also reported, as well as that of the D*s0(2317) and D*s1(2460) resonances and other states not yet identified experimentally. Being the first calculation incorporating open-charm vector mesons at finite temperature in a self-consistent fashion, it brings up the opportunity to discuss the medium effects on the open-charm sector under the perspective of chiral and heavy-quark spin symmetries.
