Abstract We construct a new class of exact solutions for shear-free, spherically symmetric radiating stars undergoing gravitational collapse in the presence of pressure anisotropy. Starting with the static metric potentials, we specialise the parametric family to the inhomogeneous anisotropic subclass n=-\, 2 n = - 2 and carry out a complete dynamical and thermodynamic analysis of this configuration. The interior solution, obtained in closed form, satisfies the standard regularity and energy conditions (null, weak, strong, and dominant), and is matched across the stellar boundary to an exterior Vaidya spacetime through the appropriate junction conditions. The configuration admits an initially static perfect-fluid limit and evolves smoothly into a dissipative collapse driven by radiative heat transport. A numerical study is also performed, wherein the effect of the anisotropy parameter on radial profiles and temporal evolutions of the density, pressures, heat flux, collapse rate, redshift, luminosity, and interior temperature is studied. The energy conditions are verified. The results demonstrate that increasing pressure anisotropy strengthens the matter variables, accelerates the contraction rate and enhances thermal dissipation throughout the radiating phase.
