I am wondering where can I find the Morse index of the most famous examples of minimal surfaces in $\mathbb{R}^3$, such as the cathenoid, the helicoid, etc.
Is there any general standard technique to estimate the Morse index of a minimal hypersurface in $\mathbb{R}^n$?
I have briefly checked the book A Course in Minimal Surfaces, by Colding and Minicozzi, but I couldn't find an answer to my questions.
Any help or reference will be very much appreciated!
