I believe the answer is:

pulsar

I'm a little stuck... Click here to teach me more about this clue!

'star' is the definition.
(pulsar is a kind of star)

'is left in america to bathe in publicity' is the wordplay.
'is left' is a reversal indicator.
'in' becomes 'lu' (I can't justify this - if you can you should believe this answer much more).
'america' becomes 'sa' (South America, one of the Americas).
'to bathe in' indicates putting letters inside.
'publicity' becomes 'pr'.
'lu' backwards is 'ul'.
'ul'+'sa'='ulsa'
'ulsa' going into 'pr' is 'PULSAR'.
