Abstract<br />
We classify embeddings <strong>of</strong> algebraic groups as open orbits in affine varieties, generalizing results<br />
from toric geometry to connected reductive groups. In particular, we show that an embedding is<br />
determined by the set <strong>of</strong> one-parameter subgroups that have a limit in the embedding. We then<br />
investigate the structure <strong>of</strong> such sets <strong>of</strong> one-parameter subgroups and how their properties reflect<br />
properties <strong>of</strong> the associated embedding.<br />
