Martin Crow and Simon Dawes have been busy taking more measurements of Exoplanet transits for the ExoClock project. Below are some of their latest ones.
”TrES-2b (also known as Kepler-1b or GSC 03549-02811b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System in Draco. The planet was identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it. Reflecting less light than charcoal, on the surface the planet is said to be pitch black. The planet’s mass and radius indicate that it is a gas giant with a bulk composition similar to that of Jupiter. Unlike Jupiter, but similar to many planets detected around other stars, TrES-2b is located very close to its star and belongs to the class of planets known as hot Jupiters. This system was within the field of view of the Kepler spacecraft. It was discovered on August 21, 2006 by the Trans-Atlantic Exoplanet Survey (TrES) by detecting the transit of the planet across its parent star using Sleuth (Palomar Observatory, California) and PSST (Lowell Observatory, Arizona), part of the TrES network of 10–cm telescopes. The discovery was confirmed by the W. M. Keck Observatory on September 8, 2006, by measuring the radial velocity of the star that hosts TrES-2b.” Ref:https://en.wikipedia.org/wiki/TrES-2b
HAT–P–37b is an exoplanet in the constellation Draco.
”HAT-P-37 b is a gas giant exoplanet that orbits a G-type star. Its mass is 1.169 Jupiters, it takes 2.8 days to complete one orbit of its star, and is 0.0379 AU from its star. Its discovery was announced in 2011.” Ref:https://science.nasa.gov/exoplanet-catalog/hat-p-37-b/
”Qatar-4b is a super-jupiter orbiting the star Qatar-4 every 1.8 days in Andromeda. It was discovered in 2016 by the Qatar Exoplanet Survey (QES).
This planet has a very short orbit, with only 1.8 days for it to complete an orbit around Qatar-4. The period corresponds with a separation of around 0.03 AU, which is almost 20 times closer than Mercury is to the Sun. Despite that, it has a perfectly round orbit. Since the host is an active star, Qatar-4 may be destroyed by tidal waves from the star.” Ref:https://en.wikipedia.org/wiki/Qatar-4b
”TrES-3b is an extrasolar planet orbiting the star GSC 03089-00929. It has an orbital period of just 31 hours and nearly twice the mass of Jupiter.
The planet TrES-3b is named Umbäässa. The name was selected in the NameExoWorlds campaign by Liechtenstein, during the 100th anniversary of the IAU. In the local dialect of southern Liechtenstein, Umbäässa is a small and barely visible ant.
