The Formation of Planets
Where do we come from, and are we alone in the universe? This is one of the questions many people may ask. Since the first exoplanet was discovered outside of our solar system in 1995, more than 700 exoplanets have been found. Some of them might have environment where life could exist, suggesting possible discovery of life in near future. On the other hand, many exoplanets are very different from those in our solar system, as well. It is therefore getting more important to understand how these planets are formed. Planets are disks around young stars, called protoplanetary disks, are formed as by-products of star formation, and are mostly observed at infrared and radio wavelengths. Such observations of protoplanetary disks at infrared and radio wavelengths have been carried out with telescopes at Mauna Kea, Hawaii, including Subaru telescope and Submillimeter Array. Join us as Dr. Ohashi will introduce infrared and radio observations, which are different from those carried out in visible light, and summarize observations of protoplanetary disks using Subaru telescope and Submillimeter Array.
Nagayoshi Ohashi is currently associate director of Subaru Telescope and a professor at National Astronomical Observatory of Japan. Before he joined Subaru Telescope, he worked at Institute of Astornomy and Astrophysics in Academia Sinica, Taiwan, working for Submillimeter Array, which is another telescope at Mauna Kea, Hawaii. He has been staying at Hilo for several years to work on these telescopes.
On the first Saturday of each month, the Visitor Information Station (VIS) hosts The Universe Tonight, a special presentation on the current research and discoveries occurring on Mauna Kea. The presentation begins at 6:00 PM and is followed by the regular evening stargazing program at the VIS.
The Universe Tonight typically features an astronomer from one of the observatories on Mauna Kea giving a presentation on recent observations and discoveries from their telescope. Observatories are on a rotating schedule. If you would like to know about upcoming presentations, please call the VIS at (808) 961-2180 during operational hours.
