US high school kids discover four exoplanets which are 200 light years away from Earth

Two students from United States have become youngest to discover four new exoplanets situated 200-light-years away from Earth. 16-year-old junior Kartik Pinglé and 18-year-old senior Jasmine Wright were part of Student Research Mentoring Program (SRMP) at Center for Astrophysics at Harvard & Smithsonian, when y me astonishing discovery. aim of this program is to select students for Harvard University and Massachusetts Institute of Technology (MIT). After being selected, students can work with ir mentors on a research project that has a duration of one year. 

Exoplanets discovered

students were directed by astrochemist Clara Sousa-Silva and mentored by Tansu Daylan, a postdoc at MIT Kavli Institute for Astrophysics and Space Research. As per press release by Harvard, Sousa-Silva said, “It’s a steep learning curve. By end of program, students can say y’ve done active, state-of--art research in astrophysics”. Under project, two students studied and analyzed data from Transiting Exoplanet Survey Satellite. 

team closely observed TESS Object of Interest (TOI) 1233 which is a bright Sun-like star close to Solar System. After that, it focussed on spotting any presence of planets that were rotating around star. For this, y narrowed in on TOI-1233’s light.

y finally discovered four exoplanets revolving around TOI 1233. Three of se are identified as sub-Neptunes. y take between six and 19.5 days to orbit around TOI-1233. fourth planet has been described as a super-Earth due to its large size and rocky topography.

Talking about his experience, Wright said, “I was very excited and very shocked”. He ded, “We knew this was goal of Daylan’s research, but to actually find a multiplanetary system, and be part of discovering team, was really cool”. ir mentor, Daylan said, “Our species has long been contemplating planets beyond our solar system and with multi-planetary systems, you’re kind of hitting jackpot”. He ded, “ planets originated from same disk of matter around same star, but y ended up being different planets with different atmospheres and different climates due to ir different orbits. So, we would like to understand fundamental processes of planet formation and evolution using this planetary system”.
