The Sixth International Conference on Mars Polar Science and Exploration
Mars polar research Mars Polar Science
2016/7/21
The Sixth International Conference on Mars Polar Science and Exploration will be held September 5–9, 2016, at the University of Iceland in Reykjavik, Iceland. Reykjavik was chosen as the site of the s...
The Solar Dynamics Observatory (SDO) was launched in February 2010 and is now providing an unprecedented view of the solar activity at high spatial resolution and high cadence covering a broad range o...
Rossby waves and polar spots in rapidly rotating stars: Implications for stellar wind evolution
magnetic fi eld – Stars: activity – Stars: starspots – Stars: oscillations – Physical data and processes: Magnetohydrodynamics
2011/10/10
Rapidly rotating stars show short-period oscillations in magnetic activity and polar appearance of starspots. The aim of this paper is to study large-scale shallow water waves in the tachoclines of ra...
High-Entropy Polar Regions Around the First Protostars
High-Entropy Polar Regions the First Protostars
2011/1/13
We report on simulations of the formation of the first stars in the Universe, where we identify regions of hot atomic gas (fH2 < 10-6) at densities above 10-14 g/cc, heated to temperatures ranging bet...
Detection of Supergranulation Alignment in Polar Regions of the Sun by Helioseismology
convection — Sun helioseismology
2010/11/10
We report on a new phenomenon of ‘alignment’ of supergranulation cells in the polar regions of the Sun. Recent high-resolution datasets obtained by the Solar Optical Telescope (SOT) onboard the Hinode...
An unified polar cap/striped wind model for pulsed radio and gamma-ray emission in pulsars
Pulsars general - Radiation mechanisms non-thermal - Gamma rays
2010/11/16
Thanks to the recent discovery by Fermi of about fifty new gamma-ray pulsars, it becomes possible to look for statistical properties of their pulsed high-energy emis-sion, especially their light-curve...
X-rays and Gamma-rays from Cataclysmic Variables: The example case of Intermediate Polar V1223 Sgr
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/23
The accretion of matter onto intermediate polar White Dwarfs (IPWDs) seems to provide attractive conditions for acceleration of particles to high energies in a strongly magnetized turbulent region at ...
Prediction of Peaks in Wolf Numbers in Cycle-24 according to Actual Numbers of Polar Faculae
Polar faculae sunspots dynamo Wolf number
2010/9/15
Previous investigations by Makarov et al. have shown a relation between the peaks in the number of polar faculae and the peaks in the Wolf number. In cycles 20 and 22 the delay between peaks in polar ...
IGR J16547-1916/1RXS J165443.5-191620 -- a New Intermediate Polar from the INTEGRAL Galactic Survey
cataclysmic variables intermediate polars white dwarfs
2010/11/11
We present the results of our optical identification of the X-ray source IGR J16547-1916 detected by the INTEGRAL observatory during a deep all-sky survey. Analysis of the spectroscopic data from the ...
During winter and springtime, the flow above Antarctica at high altitude (upper troposphere and stratosphere) is dominated by the presence of a vortex centered above the continent. It lasts typically ...

Accumulation and erosion of south polar layered deposits in the Promethei Lingula region, Planum Australe, Mars
Promethei Lingula region geologic mapping Mars
2009/6/1
The geologic mapping of south polar layered deposits in the Promethei Lingula region, Planum Australe, Mars, indicates that aeolian-based South Polar Layered Deposit accumulation and erosion were cont...
Recent aeolian erosion and deposition in the north polar plateau of Mars
aeolian erosion Mars north polar plateau
2009/6/1
We have identified extensive dark regions in the north polar plateau of Mars, which are largely free of surface water-ice. We propose that represent zones of recent sedimentary accumulation.
