Rousseff's vice president, Temer has served as acting president since May, when her impeachment indictment began. He will now serve as president through 2018.
The Brazilian Senate voted 61-20 to impeach Rousseff earlier on Wednesday, following three days of debate. The former president faced charges of corruption. She denied the accusations, calling them politically motivated.
"These are pretexts to overthrow a legitimate government through an impeachment crime without responsibility," she said. "We are one step closer to a serious institutional breakdown. We are one step closer to achieving a real coup."
While Rousseff could have been barred from seeking future public office for eight years according to Brazilian law, the Senate determined that she will maintain her political rights.
