I started working with him in January 2017. From January to March I worked on developing a CGI website where I have an interactive table showing various different images of jupiter with different onmouseover. From March to May I worked on navigating Jupiter images from Hubble telescope. navigating is important because it matches longitude and latitue coordinates onto the image of the planet. From May to November 2017 I worked on helping Mike complete his "A new dark spot on neptune" paper. I am the third author and the paper is fully published on February of 2018 on the astronomical journal. I navigated all of the Neptune images form OPAL 2015,2016,2017 survey of Neptune. I also made limb-darkening corrected images so that users can see any dark spots that might be on the planet. I used IDL to figure out what k constant to use to do the limb darkening correction. I also made graphes of background atmosphere as well as the brightness of particular parts of the planets. (contrast plots). In Fall 2017, I navigated some Uranus images and found some white clouds that could be new features on the planet. In 2018, I navigated Saturn images as well as more Jupiter images as well as OPAl 2018 Neptune images.
I wrote IDL program to read in several Neptune images and create excel tables about the atmosphere's average emission angle, I/F. I am expecting Joshua, a grad student in Earth and Planetary Science (UC Berkeley) to publish a paper about radioactive trasfer of Neptune in which I am a coauthor.
After February 2018, I started working on my own project where I try to predict how often dark spots show up on Neptune. I used hubble telescopes all previous images of Neptune in the 400 to 500 nm wavelength to see what the observed frequency of dark spot is then used monte-carlo simulation to account for years in which there is no neptune data as well as latitudes that are not imaged to make the prediction. I used excel to make most of my graphes and IDL to perform monte-carlo simulation. Latex to type up the paper. Mike gave me suggestions of what the outline of the project is as well as helped to calibrate images for me to navigate. I submitted this paper on Nov 8 2018 to the Astrophysical Journal. The authors are me and Mike Wong and Amy Simon. The paper is called Lifetimes and Occurrence Rates of Dark Vortices on Neptune from 23 Years of Hubble Space Telescope Images. It was accepted on February 13 2019 to the Astronomical Journal. There are a Berkeley news as well as a Daily Cal articles about this.
In July 2018, Mike is going to the COSPAR conference in Pasadena to present our work. The slides he used in his presentation has my name in the first page as well as two of my graphs in the last page. This is the slide with two graphs I made. It shows the historic coverage of Neptune's longitude on a given latitude. I plan to include these two graphs in my prediction of dark spot frequency paper.
In Summer 2018, I took a course/internship with Howard , Alma Ceja, Sarah Blunt as the instructors who taught me over google hangout more skills relevant to exoplanet research such as different techniques to detect exoplanet, writing MYSQL to search the GAIA database, graphing things from downloaded excel table from NASA exoplanet archive. This course/internship inspired me to create this website. This course taught me introductory R language and how to write a proposal. The below is the proposal I wrote as part of the class.
