Carrie Fisher, the actress best known for her portrayal of Princess Leia in the original "Star Wars" trilogy, died Tuesday at the age of 60. Fisher’s death follows an in-flight emergency over the weekend as she flew from London to Los Angeles.

Details surrounding that medical emergency weren’t completely clear but many news outlets reported that she had suffered a heart attack and was taken into intensive care once the plane had grounded. A member of her family, not confirming anonymously sourced quotes, told said before her death that all of the details surrounding her illness were unclear.

Fisher, who owned a Spanish-style home in Beverly Hills, California, leaves behind a sizeable fortune that has been estimated to be around $25 million by some sites and $5 million by other sites. That net worth, when compared to other "Star Wars" cast members like Harrison Ford, is relatively low and has been blamed on the then-19-year-old Fisher singing away her likeness when she signed up for the profitable franchise.

Fisher has made money from other ventures than "Star Wars," though. She authored “Postcards from the Edge,” a 1987 semi-autobiographical best-selling novel that was later adapted into a motion picture. She also wrote a one-woman play from the screenplay for the movie called "Wishful Drinking."

Her most recent book, released this year, was the “Princess Diarist.” She had been traveling to promote that book, which is a memoir of her life, around the time she was filming the "Star Wars" movies.  The book had attracted quite a bit of attention for her divulgence of juicy secrets including her behind-the-scenes romance with Ford on the "Star Wars" set.

It was not immediately clear what would happen to Fisher’s estate, which would likely be determined through a will from the actress. Fisher is survived, according to the New York Times, by her one child, Billie Lourd, her brother and two half-sisters. She was not married at the time of her death.
