Observations of magnetic fields in hot stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
The presence of magnetic fields at the surfaces of many massive stars has been suspected for decades, to explain the observed properties and activity of OB stars.
WASP-32b: A transiting hot Jupiter planet orbiting a lithium-poor, solar-type star
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/28
We report the discovery of a transiting planet orbiting the star TYC 2-1155-1. The star, WASP-32, is a moderately bright (V=11.3) solar-type star (Teff=6100 +- 100K, [Fe/H] = -0.13 +- 0.10).
Extremely large and hot multilayer Keplerian disk around the O-type protostar W51N: The precursors of the HCHII regions?
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
We present sensitive high angular resolution (0.57$''$-0.78$''$) SO, SO$_2$, CO, C$_2$H$_5$OH, HC$_3$N, and HCOCH$_2$OH line observations at millimeter and submillimeter wavelengths of the young O-typ...
Comparison of current models for Hot Jupiters to the sample of transiting exoplanets
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/24
A growing number (over 100!) of extra-solar planets (ESPs) have been discovered by transit photometry, and these systems are important because the transit strongly constrains their orbital inclination...
Physics of the Sun’s Hot Atmosphere
Solar atmosphere X-ray EUV emission coronal heating solar wind
2010/9/16
This article briefly overviews the physics of the Sun’s hot atmosphere,using observations from recent solar spacecrafts: Yohkoh, SOHO,TRACE and RHESSI.
In the present work we calculate the adiabatic index of neutron stars formed by hadronic or quarkionic matter, under two possible conditions, with and without trapped neutrinos, and for two values of ...
The cold-water coral community as a hot spot for carbon cycling on continental margins: A food-web analysis from Rockall Bank (northeast Atlantic)
The cold-water coral community carbon cycling continental margins: A food-web analysis Rockall Bank
2014/4/17
We present a quantitative food-web analysis of the cold-water coral community, i.e., the assembly of living corals, dead coral branches and sediment beneath, associated with the reef-buildingLophelia ...
Ocean acidification hot spots: Spatiotemporal dynamics of the seawater CO2 system of eastern Pacific coral reefs
Ocean acidification hot spots Spatiotemporal dynamics the seawater CO2 system eastern Pacific coral reefs
2014/4/16
Seawater CO2system dynamics were assessed from eastern Pacific reef sites in Panama ′ over 5 consecutive years(2003–2008) and twice in the Gala ′ pagos Islands (2003 and 2009). The seawater CO2system ...
Not So Black? The Statistics of Albedo and Energy Recirculation on Hot Exoplanets
data analysis — (stars:) planetary systems
2010/3/8
[Abridged] We use a simple analytic model to analyze all of the published photometric observations of exoplanets. Our model has two parameters: the planets' Bond albedo, A, and its heat recirculation ...
Thermal analysis and Hot-stage Raman spectroscopy of the basic copper arsenate mineral
Copper Arsenate Olivenite Cornwallite Cornubite Clinoclase thermal stage Raman spectroscopy Euchroite
2011/11/10
The thermal analysis of euchroite shows two mass loss steps in the temperature range 100–105 °C and 185–205 °C. These mass loss steps are attributed to dehydration and dehydroxylation of the mineral. ...
Discrimination of hot versus cold avalanche deposits: Implications for hazard assessment at Mount Meager, B.C.
hot versus cold avalanche deposits hazard assessment Mount Meager, B.C.
2009/12/10
The surficial deposits surrounding the Mount Meager volcanic complex include numerous avalanche deposits. These deposits share many attributes: (a) they are nearly monolithologic and comprise mainly i...
Response of the Nevzorov hot wire probe in clouds dominated by droplet conditions in the drizzle size range
Nevzorov hot wire probe clouds droplet conditions drizzle size range
2010/2/8
During the airborne research mission ASTAR 2004 (Arctic Study of Tropospheric Aerosols, Clouds and Radiation) performed over the island of Svalbard in the Arctic a constant-temperature hot-wire Nevzor...
Numerical simulations of the charging of dust particles by contact with hot plasmas
Numerical simulations dust particles hot plasmas
2009/11/3
Charging of individual dust particles in contact with hot plasmas is studied by numerical methods. The dust particle is treated as a rigid solid body, composed by either perfectly insulating or conduc...
