Hello!
I was wondering if there is a way to find out how much energy is being distributed in a certain frequency after computing fourier analysis ? I have the fundemental frequency showing me the most power is going into it - but I was wondering if there is a way to compute how much of the total power is going into the main pulsation ??
Maybe im just not understanding what " power " means in this instance
Any help is appreciated!
Thank you
Hi Ariella,
Have you considered or done Brad Walters AAVSO course on using Vstar . There are two levels.
I don't what your level of physics is. The standard text on stellar pulsations and still good is an old (~1990) text by Cox.
A newer and more advanced one is "Asteroseismology" by Aerts, Christensen-Dalsgaard, and Kurtz.
Maybe the thesis of Dominic Bowman " Amplitude Modulation and Energy Conservation of Pulsation Modes in Delta Scuti Stars" would be helpful.
