Polynomial Approximants for the Calculation of Polarization Profiles in the He I 10830 Å Multiplet
The He I multiplet at 10830 Å is formed in the incomplete Paschen-Back regime for typical conditions found in solar and stellar atmospheres. The positions and...
Populations of High-Luminosity Density-bounded H II Regions in Spiral Galaxies: Evidence and Implications
We present evidence that the H II regions of high luminosity in disk galaxies may be density bounded, so that a significant fraction of the ionizing photons...
PORTA: A three-dimensional multilevel radiative transfer code for modeling the intensity and polarization of spectral lines with massively parallel computers
The interpretation of the intensity and polarization of the spectral line radiation produced in the atmosphere of the Sun and of other stars requires solving a...
Portrait of the Polana-Eulalia family complex: Surface homogeneity revealed from near-infrared spectroscopy
The inner asteroid belt is an important source of near-Earth asteroids (NEAs). Dynamical studies of the inner asteroid belt have identified several families...
Position-dependent infrared spectroscopy of M82 - 100,000 Orion nebulae?
It is reported that 8-13-micron spectra have been obtained at several positions across the extended emission region of M82. No major differences among the...
Position-velocity diagrams of ionized gas in the inner regions of disk galaxies
We use long-slit spectroscopy along the major axis of a sample of 23 nearby disk galaxies to study the kinematic properties of the ionized-gas component in...
Possible detection of a bimodal cloud distribution in the atmosphere of HAT-P-32 A b from multiband photometry
We present high-precision photometry of eight separate transit events in the HAT-P-32 planetary system. One transit event was observed simultaneously by two...
Observations of the Jupiter were carried out using a refined version of the stellar seismometer with a sensitivity of better than 50 cm/s. The observations...
