Synthetic Observed-Band Light Curves of Delta Cephei from MESA-RSP Models
Zuhoor Elahi, Christopher Sirola, Wafa Gull
Observed-band light curves provide a stronger test of Cepheid pulsation models than period matching alone, because the measured photometric amplitude depends on the phase-dependent…

Nonlinear MESA-RSP Modeling of Delta Cephei: Period Matching, Amplitude Control, and Model-Acceptance Diagnostics
Zuhoor Elahi, Christopher Sirola, Wafa Gull
Delta Cephei is the prototype classical Cepheid and a useful target for testing whether a one-dimensional nonlinear radial-pulsation workflow can satisfy more than a period constra…

Native-Opacity Sensitivity of a Fixed Delta Cephei MESA-RSP Pulsation Model
Zuhoor Elahi, Christopher Sirola, Wafa Gull
Radiative opacity is one of the central microphysical inputs controlling the thermal response of Cepheid envelopes and the driving or damping of radial pulsations. We present a con…
