Biography

Professor Andrew W. Howard works in the field of Astronomy at the California Institute of Technology. His research primarily focuses on extrasolar planets and their formation and evolution, particularly studying planets orbiting stars other than the Sun. Utilizing telescopes located in Hawaii, California, and in space, his research group is dedicated to discovering and characterizing these planets, allowing them to determine their physical and orbital characteristics. Through the analysis of thousands of planetary systems, Professor Howard aims to place these extrasolar planets in a broader context, especially focusing on the diversity of small planets. His investigations include understanding the structures and compositions of these planets, which vary significantly due to different mixtures of the essential planetary ingredients, such as hydrogen gas, water, rock, and iron. Additionally, he emphasizes the comparison of these findings to the planets in our Solar System, specifically Neptune and Earth, which exemplify the traits of low-density ice giants and high-density rocky planets.
