In the stretching mode region, the shape of the band is not altered too much as can be seen on Fig. 3 (middle panel), even when the substructure appears in the 15.2 µm band. The temperature at which the bending mode shows a triple substructure is roughly ...

EUV and X-ray Spectroscopy of the Active Sun
... This thesis strives to improve our understanding of solar activity, specifically the behaviour of solar flares and coronal mass ejections. An investigation into the hydrodynamic evolution of a confined solar flare was carried out using RHESSI, CDS, GOES and TRACE. Evidence for pre-flare heating, exp ...

Astronomy 112: The Physics of Stars Class 1 Notes
... We can actually learn a tremendously larger amount by measuring the spectrum of stars. That’s because a real stellar spectrum isn’t just a simple continuous function like a blackbody. Instead, there are all sorts of spiky features. These were first studied by the German physicist Fraunhofer in 1814 ...

This is due to the strong energy losses they undergo in the magnetic field of the Milky Way. In fact cosmic electrons reaching Earth with energies higher than 1 TeV ...

Non-radiative inelastic processes in lithium-helium ion
... According to the Big Bang nucleosynthesis theory, lithium is the heaviest stable element produced in this event (Burles et al. 2001). After the initial period, when in the rapidly expanding Universe matter and radiation were in close thermal contact, the Universe became transparent and temperature w ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
