Dr. Ueta is an associate professor in the Department of Physics and Astronomy. His research interests include
(1) stellar evolution: particularly looking into the late stages of evolution from the Red Giant to the Planetary Nebula phases involving mass loss processes
(2) astropaleontology: investigation into the history of stellar mass loss by observing the circumstellar gas/dust distribution
(3) astromineralogy: study of the composition and formation of circumstellar and interstellar matter, especially dust grains
(4) radiative transfer in dusty media
(5) observations of circumstellar phenomena using optical, infrared, sub-mm, and radio
(6) interactions between stellar winds and the interstellar medium
He is an active user of various space-based and ground-based observatories around the world. Recently, he has been involved in international consortia using the latest infrared telescopes such as Spitzer (US), AKARI (Japan) and Herschel (Europe).
There are always some research opportunities for students. If you are interested in any of these topics and related ideas, please do not hesitate to contact me!
Dr. Ueta has recently spent his 10-month sabbatical leave (06/2013-03/2014) as an guest research fellow at the Institute of Space and Aeronautical Science (ISAS) of the Japan Aerospace eXploration Agency (JAXA) in Sagamihara, Japan. His fellowship was sponsored by the Japan Society for the Promotion of Science via their invitation fellowship program.
As of January 2015
List of Publications (via ADS) (clicking the left link will generate a list of publications)
Far-infrared emission from OH+ molecules was detected for the first time from planetary nebulae based on observations made as part of the Herschel Planetary Nebula Survey (HerPlaNS, Dr. Ueta is the PI of this project) and other programs.
A bow-shock like "wake" due to intersctions between stellar winds and the interstellar medium around the low-mass asymptotic giant branch star R Hya was discovered in the far-IR emission for the first time around this type of star.
