Detection of Ks-band Thermal Emission from WASP-3b
planetary systems Ks-band Thermal Emission WASP-3b
2012/2/23
We report the detection of thermal emission from the hot Jupiter WASP-3b in the KS band, using a newly developed guiding scheme for the WIRC instrument at the Palomar Hale 200in telescope. Our new gui...
Infrared and radio study of the W43 cluster: resolved binaries and non-thermal emission
Stars: binaries – Stars: Wolf-Rayet – X-rays: stars – Radio continuum: stars – Gamma rays: stars – Infrared: stars
2011/10/9
Context: The recent detection of very high-energy (VHE) gamma-ray emission from the direction of the W43 star-forming region prompted us to investigate its stellar population in detail in an attempt t...
Variability of the SiO thermal line emission toward the young L1448-mm outflow
Variability SiO emission L1448-mm outflow
2011/10/8
The detection of narrow SiO thermal emission toward young outflows has been proposed to be a signature of the magnetic precursor of C-shocks. Recent modeling of the SiO emission across C-shocks predic...
Center-to-Limb Variation of Radio Emissions from Thermal-Rich and Thermal-Poor Solar Flares
acceleration of particles—Sun: fl ares—Sun: magnetic fi elds—Sun:radio radiation—Sun: X-rays, gamma rays
2011/9/30
A statistical analysis of radio flare events was performed by using the event list of Nobeyama Radioheliograph in 1996-2009. We examined center-to-limb variations of 17GHz and 34GHz flux by dividing t...
Detection of a Thermal Spectral Component in the Prompt Emission of GRB 100724B
Detection of a Thermal Spectral Component in the Prompt Emission of GRB 100724B
2011/1/10
Observations of GRB 100724B with the Fermi Gamma-Ray Burst Monitor (GBM) find that the spectrum is dominated by the typical Band functional form, which is usually taken to represent a non-thermal emis...
Thermal evolution and lifetime of intrinsic magnetic fields of Super Earths in habitable zones
Thermal evolution intrinsic magnetic fields
2011/1/11
We have numerically studied the thermal evolution of various-mass terrestrial planets in habitable zones, focusing on duration of dynamo activity to generate their intrinsic magnetic fields, which may...
The 1.6 micron near infrared nuclei of 3C radio galaxies: Jets, thermal emission or scattered light?
infrared nuclei 3C radio galaxies
2011/1/11
Using HST NICMOS 2 observations we have measured 1.6-micron near infrared nuclear luminosities of 100 3CR radio galaxies with z<0.3, by modeling and subtracting the extended emission from the host gal...
We present a study of the radio emission from a massive runaway star. The star forms a bow shock that is clearly observed in the infrared. We have performed VLA observations under the assumption that ...
Molecular environment and thermal X-ray spectroscopy of the semicircular young composite supernova remnant 3C 396
ISM individual (3C 396 G39.2− 0.3) – ISM molecules – supernova remnants
2010/11/15
We have investigated the molecular gas environment of the semicircular composite supernova rem-
nant (SNR) 3C 396 in multiwavelengths and performed a Chandra spatially resolved thermal X-ray
spectro...
A Model for Thermal Phase Variations of Circular and Eccentric Exoplanets
methods data analysis planetary systems
2010/11/9
We present a semi-analytic model atmosphere for close-in exoplanets that captures the essential
physics of phase curves: orbital and viewing geometry, advection, and re-radiation. We calibrate the mo...
Impact of MHD Turbulence on Thermal Wind Balance in the Sun
instabilities—rotation—sun magnetohydrodynamics— stars sun
2010/11/15
The possible role of magneto-rotational instability (MRI) and its driven MHD turbulence in
the solar interior is studied on the basis of the linear and nonlinear theories coupling with
physical para...
High-spatial-resolution imaging of thermal emission from debris disks
circumstellar matter infrared stars – planetary systems
2010/11/11
We have obtained sub-arcsec mid-IR images of a sample of debris disks within 100 pc. For our sample of nineteen A-type debris disk candidates chosen for their IR excess, we have resolved, for the firs...

On the Inference of Thermal Inversions in Hot Jupiter Atmospheres
Thermal Inversions Hot Jupiter Atmospheres
2011/1/10
Several studies in the recent past have inferred the existence of thermal inversions in some transiting hot Jupiter atmospheres. Given the limited data available, the inference of a thermal inversion ...
