Sentences with phrase «magnetic field loss»

Jakosky and the MAVEN team tie the magnetic field loss to the atmospheric loss on Mars.

Not exact matches

They plan to examine data from other instruments on MAVEN to see if escaping particles map to the same regions where they see reconnected magnetic fields to confirm that reconnection is contributing to Martian atmospheric loss and determine how significant it is.

The new research, published today in the journal Geophysical Research Letters, explains that this atmospheric loss is driven by a polar wind powered by an interaction between sunlight, the solar magnetic field and the molecules present in the upper atmosphere.

In the absence of a magnetic field, Tarduno says the protons that make up the solar winds would have ionized and stripped light elements from the atmosphere, which, among other things, resulted in the loss of water.

In the end it turned out that some configurations seem to be more favorable than others, and turbulent transport losses may be reduced by clever optimization of the magnetic field, hence increasing the efficiency of a prospective power plant.

Cusp devices were investigated in the 1960s and 1970s but were largely abandoned because particles leak out through gaps between the various magnetic fields leading to a loss of temperature.

«Because rock in the deep mantle moves less than a centimeter a year, we know the LLSVP is ancient, meaning it may be a longstanding site for the loss of magnetic field strength,» said Tarduno.

The gauntlet Juno ran at Jupiter held many chances for catastrophe: The spacecraft might have been knocked out by intense magnetic fields (at that distance, 20 times stronger than Earth's), ionizing radiation (a total dose of 265 rads — more than enough to kill a human being), dust particles from Jupiter's rings (from which the main engine was completely unshielded) or loss of power if the solar arrays were unable to reorient to the sun.

With the VLBA's capability to make detailed maps of the star's magnetic field and to monitor the mass - loss process, the researchers hope to shed some light on this longstanding mystery of stellar physics.

C. Carreau, ASPERA - 4 & MAG teams, Venus Express, ESA Annotated image illustrating loss of hydrogen through plasma wake Venus may have lost oceans of water due to a runaway greenhouse effect which evaporated water into the upper atmosphere, where ultraviolet light dissociated water into ionized atomic hydrogen and oxygen (some later incorporated into carbon dioxide) that were blown away by the Solar wind due to the lack of a strong magnetic field like the Earth's (more).

The increased equatorward wind at middle latitudes tends to push the ionosphere higher up along magnetic field lines, where the loss rate is lower.
