Increase the dot from \dot and ring from \mathring in size

Question

Context : I'm using \dot{} and \mathring{} commands, but they are way too small to be noticed if you are not reading with full attention. Sometimes, it is hard to distinguish between them both.

Illustration for the \dot{} command :

Illustration for the \mathring{} command :

My problem : I would like to make both the dot and the ring bigger so that they are easier to read. I have a book in which the ring looks better than what I have, so I'm guessing it is possible even if I can't find a clue about how to do it. Detexify is not suited for this kind of research nor did I find answers on the MathJax basic tutorial. Somehow I tried the \Huge{} command, but it changed nothing.

I take any suggestion, especially if they are quite simple ! Thanks for your time !

Answer 1

I am using the accents package: this package center the symbols below.

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}
\usepackage{accents}


\begin{document}
\[\accentset{\circ}{G}\]

\[\accentset{\bigcirc}{G}\]


\[\accentset{\bullet}{G}\]

\end{document}
