"A comparison of the atmospheres of Jupiter and Saturn: Deep atmospheric composition, cloud structure, vertical mixing, and origin". I was named the UK Young Face of Fusion 2016 for EUROFusion, a Very Early Career Physics Communicator finalist from the Institute of Physics and am an author of numerous articles for Catalyst Magazine and others. Do microbes control the formation of giant copper deposits? © 2021 Forbes Media LLC. Our new findings suggest that previous non-detections were caused by opaque, high-up clouds obscuring the parts of the atmosphere where steam is present.”. Hot Jupiters have an orbital period of less than 10 days; thus, their atmospheres are considered to be very exotic because of the high temperatures. The hot Jupiter WASP-148b is rather unusual, since it has a sibling planet, WASP-148c in a 35-day orbit (Hébrard et al. Application to the day/night cold trap in HD 209458b}, author={V. Parmentier and A. Last year, a team led by the University of Exeter was awarded nearly 200 hours on the NASA/ESA Hubble Space Telescope to examine eight planets using this technique — the largest survey of its type to date. “Seeing steam in two exoplanets is a great confirmation of current theory. However, only two self-consistent MHD models of the in-teraction of planetary magnetic fields with atmospheric dy-namics have been conducted (Batygin et al. The effects of the dissociation of these species will be varied and must be carefully accounted for. I. The results presented at the National Astronomy Meeting represent initial findings and work by the team is still ongoing to analyze all the data from the eight-planet Hubble survey. exoplanet gas giants, having masses comparable to the mass of Jupiter and semimajor axes shorter than 0.1 AU, are a unique class of objects. These types of planets are known as gas giants. A team of international researchers, led by astrophysicists from the University of Exeter, Columbia University and NASA Goddard Institute for Space Studies, used state-of-the-art modelling techniques to extensively study the atmosphere of a ‘hot Jupiter’ found 150 lightyears from Earth. • Atreya, Sushil K.; Wong, M. H.; Owen, T. C.; Mahaffy, P. R.; Niemann, H. B.; de Pater, I.; Drossart, P.; Encrenaz, T. (October–November 1999). The first, very hot planet observed showed an unexpected absence of titanium oxide. The team of scientists heated up a mixture of hydrogen and carbon monoxide to temperatures of 1,100 degrees Celsius (2,000 degrees Fahrenheit) and greater. I’m also a keen science communicator and blogger who’s caught the physics bug and would like others to catch it too! LASP-led team to study evaporating atmospheres of “hot Jupiters” Posted October 31st, 2017 This artistic rendering of the CUTE spacecraft and instrument—in its sun-synchronous, geocentric orbit—shows the solar panels, communications antenna, optical system, star trackers (lower right, facing front and right), and the computer. The team also made a confirmed detection of water vapor in the atmosphere of two planets. In this work, we study such weather in hot Jupiter atmospheres using idealized cloud-free general circulation models with double-gray radiative transfer. Modeling Heat Redistribution. 2020).The system was recently observed by TESS leading to a new paper by Gracjan Maciejewski et al. I love high power lasers, the type that can set fire to things, so my research work focuses on working with mighty lasers which can be used for better particle accelerators and imaging. Credit. Hot Jupiters, i.e. & Astrophys. In this section, we briefly investigate the relationship between atmospheric chemistry and temperature structure using a semi-analytic approach. Hot Jupiters receive intense incident stellar light on their daysides, which drives vigorous atmospheric circulation that attempts to erase their large dayside-to-nightside flux contrasts. I’ve got a BSc in Physics from Imperial College London. Hot Jupiters exhibit atmospheric temperatures ranging from hundreds to thousands of Kelvin. MASCARA-2B/KELT-20b is an ultra hot Jupiter. A new class of exoplanets is beginning to emerge: planets whose dayside atmospheres more closely resemble stellar atmospheres as most of their molecular constituents dissociate. This planet orbits a star that is much hotter than our sun. New light on the complex nature of 'hot Jupiter' atmospheres. I’m a curious and keen physicist that is currently studying for an MRes in Photonics at Imperial College London where I've completed research at SLAC National Accelerator…. PMID 11543193. Opinions expressed by Forbes Contributors are their own. Hot Jupiters are giant exoplanets, similar in size to Jupiter, that orbit so close to their stars that their atmospheres can reach temperatures of 1,000-3,000 degrees Celsius. Planets that have a mass of about 10 Earths or greater and about twice the diameter or more have enough mass to hold in Hydrogen by gravity. Using the Hubble Space Telescope astronomers compare two seemingly similar “hot Jupiter ” exoplanets, finding that WASP-67 b and HAT-P-38 b have very different atmospheres.. Is it a case of nature versus nurture when it comes to two “cousin” exoplanets? Peter Gao led the team modeling hot Jupiter atmospheres to determine the types of clouds likely to occur on very hot planets around distant stars. In a unique experiment, scientists used NASA ’s Hubble Space Telescope to study two “hot Jupiter” exoplanets. doi:10.1016/S0032-0633(99)00047-1. Radiative transfer in planetary atmospheres is usually treated in the static limit, i.e., neglecting atmospheric motions.
