One of the most unlikely exoplanets discoveries were a surprise when simple terrestrial telescopes spotted a hot-Saturn exoplanet in passing as pair star. Responsible for finding it is Karen Collins, one of a group in the University of Louisville. They estimated the distance to be about 700 light-years away, in another distant solar system.
Exoplanet KELT-6b was revealed, to the general public on Tuesday, June 4, in 2019 during a meeting of the Astronomical Society's national. Its sighting was chanced when it crossed the start in one of its orbits, around the host star. This is the similar circumstance of most exoplanets that were spotted recently. The researchers noted it is similar to the exoplanet HD 209458b in its transit to its partner star.
Located in the star system Coma Berenices, adjacent to Leo which orbits and does transit the orbit locked star very fast. It is so brief because the orbit is only 7.8 days, a little more than a week. Live on that planet and a year is just a week too. It takes a mere 5 hours to finish a day, compared to ours of 24 hours a day!
If this was, by all means so short at 5 hours to orbit its star. Using the same type of scope, have found other worlds that orbit, around their stars at less than that. Spotting exoplanet KELT-6b was not easy because shorter orbit times will have the exoplanets moving so fast, for such huge objects in space. Only visible, during clear skies using the UofL's Moore Observatory. Which is provided images for examination by scientists?
An acronym KELT, means Kilodegree Extremely Little Telescope project, that is in Arizona and another in South Africa but no better than the most expensive digicams (imaging). Remarkably, these telescopes show even less advanced ones are able to spot and find exoplanets. Activities of the KELT in the north include spotting another exoplanet with a need to verify the transit and data about it.
KELTS take digital images of the sky at night, and astronomers examine the images taken from it. Points of interest are slight variations in stellar intensity, which might be a clue that a planet is passing regularly. If the anomaly is now suspected to indicate an exoplanet in transit, other telescopes are brought to bear on that suspected area. The calculations are now made to determine conclusively if there is a planet indeed.
Scientist working collaboratively with Karen Collin to narrow all parameters, the KECK (observatory) needed for the study. Using the high-powered twin Keck Observatory telescopes in Hawaii, to analyze the findings precisely and it did pay off with KELT-6b discovery. Another is ordinary telescope have just as much chance for initial discoveries too.
Several conclusions about KELT-6b were confirmed by closer observations and analysis of the data gained.
a. A giant gas-giant (KELT-6b) is revolving a locked orbit with a star as old as ours.
b. Same size as Saturn and with the same planet mass, but without rings. KELT-6b is the same as HD 209458b.
c. The discovery exoplanet is low on metals and is mostly gas like helium and hydrogen.
