The researchers focused on the transmission of high-energy X-rays and gamma rays through planetary atmospheres
The discovery also offers "a particularly lucrative observing opportunity" for studying planetary atmospheres
of an eccentric-orbit planet, the researchers said in a (http://arxiv.
This process is important for a planetary atmosphere
because it raises the temperature and pressure of a small portion of the atmosphere to a very high value so that molecules can form, which would not otherwise occur at standard atmospheric temperatures and pressures.
This behavior, unexpected in a planetary atmosphere
, is evidence of the particularly stormy Jovian upper atmosphere, not unlike a star's atmosphere," the team writes in the Aug.
Moreover, it's difficult to isolate the specific factors that make one planetary atmosphere
different from another.
to measure the thermal radio emissions of water in a planetary atmosphere
other than Earth's.
When Pluto passed in front of a star last June 9, the gradual refraction and dimming of the star's light as the planet got in the way showed a planetary atmosphere
(SN: 6/18/88, p.
This is the first evidence of two planetary atmospheres
- Neptune originally and now Uranus - showing similar variations, in both cases originating from their host star," the study notes.
Gareth Williams, a Fellow of the AMS and an atmospheric scientist who focused on the large-scale structure of planetary atmospheres
, died on 5 November 2014 at University Medical Center of Princeton, New Jersey.
Another opportunity to characterize planetary atmospheres
occurs when a planet passes behind (or is occulted by) its parent star in a secondary eclipse.
Second, the molecular weight of material around the Sun might be either much smaller, or in the case of condensed hydrogen, much larger, than found in planetary atmospheres
Levenson holds a degree in physics and writes prolifically about everything from fictional works to radiative-convective models of planetary atmospheres
A primer on methods to study planetary atmospheres
and their applications is appended.
Hazza Bani Malek, a major in mechatronics at the Higher Colleges of Technology in Ras Al Khaimah, will work with a group updating facility automation in the Electric Arc Shock Tube facility, which simulates the high enthalpy (heat) environment encountered by spacecraft entering planetary atmospheres
