The fundamental parameters of the roAp star HD 24712: A rapidly oscillator at the red edge of the instability strip

Context. There is still a debate about the nature of the mechanism that causes the pulsation excitation of the rapidly oscillating Ap stars that oscillate above the highest theoretically acoustic frequency. HD 24712 is a good test case for such a study because it is bright, its parallax accurately d...
