We study constant-roll inflation in the presence of a gauge field coupled to an inflaton. By imposing the constant anisotropy condition, we find new exact anisotropic constant-roll inflationary solutions which include anisotropic power-law inflation as a special case. We also numerically show that the new anisotropic solutions are attractors in the phase space.

Constant-Roll Inflation: Analytical Formulae for Power Spectrum and Implications for Induced Gravitational Waves
Analytical formulae for power spectrum peaks in constant-roll inflation enable parameter reconstruction from peak features and smoothed approximations for induced gravitational wave estimates.

Power-law Bianchi type I inflation with multiple vector fields
Exact power-law Bianchi type I inflationary solutions are found for one scalar field coupled to up to three vector fields, with stability governed by the relative sizes of the gauge-coupling exponents.

Kaluza-Klein inspired a model of the inflation with the inversed power law potential in Bianchi type-I universe
For a Kaluza-Klein inspired vector-scalar model in Bianchi type-I with inverse power-law potential, center manifold theory shows the isotropic scalar-dominated point E is a stable attractor, supporting isotropization.
