On the effects of clouds and hazes in the atmospheres of hot Jupiters: semi-analytical temperature-pressure profiles
planets and satellites: atmospheres – radiative transfer
2011/9/29
Motivated by the work of Guillot (2010), we present a semi-analytical formalism for calculating the temperature-pressure profiles in hot Jovian atmospheres which includes the effects of clouds/hazes a...
Pan-STARRS1 Discovery of Two Ultra-Luminous Supernovae at z ~ 0.9
Pan-STARRS1 Discovery Ultra-Luminous Supernovae z ~ 0.9
2011/10/11
We present the discovery of two ultra-luminous supernovae (SNe) at z ~ 0.9 with the Pan-STARRS1 Medium-Deep Survey. These SNe, PS1-10ky and PS1-10awh, are amongst the most luminous SNe ever discovered...
Turbulent Linewidths in Protoplanetary Disks: Predictions from Numerical Simulations
Turbulent Linewidths Protoplanetary Disks: Predictions Numerical Simulations
2011/10/11
Sub-mm observations of protoplanetary disks now approach the acuity needed to measure the turbulent broadening of molecular lines. These measurements constrain disk angular momentum transport, and fur...
Photospheric Signatures of Granular-scale Flux Emergence and Cancellation at the Penumbral Boundary
Photospheric Signatures Granular-scale Flux Emergence Cancellation Penumbral Boundary
2011/10/17
We studied flux emergence events of sub-granular scale in a solar active region. New Solar Telescope (NST) of Big Bear Solar Observatory made it possible to clearly observe the photospheric signature ...
Subsurface flows associated with rotating sunspots
Sun helioseismology, Sun interior, (Sun) sunspots
2011/10/19
In this paper, we compare components of the horizontal flow below the solar surface in and around regions consisting of rotating and non-rotating sunspots. Our analysis suggests that there is a signif...
Imaging power of multi-fibered nulling telescopes for extra-solar planet characterization
Fourier optics Nulling telescope Achromatic phase shifter Single-mode waveguide
2011/10/13
In this paper are discussed the nulling and imaging properties of monolithic pupil telescopes equipped with a focal plane waveguide array, which could be envisaged as precursor space missions for futu...
Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low Metallicity Small Magellanic Cloud (SAGE-SMC). I. Overview
Surveying Agents Galaxy Evolution Tidally-Stripped Small Magellanic Cloud
2011/10/13
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc). This motivated the SAGE-SM...
New eigen-mode of spin oscillations in the triplet superfluid condensate in neutron stars
Neutron star Superfl uidity Spin waves
2011/10/14
The eigen mode of spin oscillations with $\omega\simeq \sqrt{58/35}\Delta$ is predicted to exist besides already known spin waves with $\omega \simeq\Delta /\sqrt{5}$ in the triplet superfluid neutron...
Synthetic Spectra of Radio, Millimeter, Sub-millimeter and Infrared Regimes with NLTE approximation
Synthetic Spectra Millimeter Sub-millimeter Infrared Regimes
2011/10/10
We use a numerical code called PAKALMPI to compute synthetic spectra of the solar emission in quiet conditions at millimeter, sub-millimeter and infrared wavelengths. PAKALMPI solves the radiative tra...
We report results based on mid-infrared photometry of comet 103P/Hartley 2 taken during May 4-13, 2010 (when the comet was at a heliocentric distance of 2.3 AU, and an observer distance of 2.0 AU) by ...
Velocity measurements for a solar active region fan loop from Hinode/EIS observations
Velocity measurements solar active region observations
2011/10/8
The velocity pattern of a fan loop structure within a solar active region over the temperature range 0.15-1.5 MK is derived using data from the EUV Imaging Spectrometer (EIS) on board the Hinode satel...
Revisiting the solar tachocline: Average properties and temporal variations
Revisiting solar tachocline:Average properties temporal variations
2011/9/28
The tachocline is believed to be the region where the solar dynamo operates. With over a solar cycle's worth of data available from the MDI and GONG instruments, we are in a position to investigate no...
