What is it? I can only find the hydroboration-oxidation mechanism for alkenes, not alkynes. I don't expect you to waste your time explaining it in full to me, just a link would be fine.

Is it the just same mechanism?

From my knowledge the mechanism is same only that the tripple bond can ract twice with the borane unless you use bulky borane. If you let it react once you then get ketone or aldehyde, if it reacts twice you get probably monotopic dialcohol, but im not realy sure how stable it is so it migh eliminate water and you get aldehyde or ketone anyway
