Thermal observations of spacecraft target 1999 JU3
We propose a 1.4 hr program to observe, with IRS, the near-Earth asteroid 161273 (1999 JU3), the primary target of two proposed spacecraft missions: the...
Thermal Properties, Size Distribution, and Albedo Distribution of Jupiter-Family Comets
We present results from SEPPCoN (Survey of Ensemble Physical Properties of Cometary Nuclei), a survey of 100 Jupiter-family comets (JFCs) using the Spitzer...
Thermal-magnetic relation of a sunspot as inferred from the inversion of 1.5 μm spectral data
We present the thermal-magnetic relation in a simple, isolated sunspot deduced from the inversion of 1.56 μm spectropolarimetric data. Due to the high Zeeman...
THERMAP: a mid-infrared spectro-imager based on an uncooled micro-bolometer for space missions to small bodies of the solar system
We report on the feasibility study of a mid-infrared (8-18 µm) spectro-imager called THERMAP, based on an uncooled micro-bolometer detector array. Due to the...
Thermodynamical properties of granulation in active regions.
A two-dimensional spectroscopic study of two solar active regions is presented. A magnetic filling factor has been defined, and a new technique to separate...
Thermonuclear bursts from slowly and rapidly accreting neutron stars
Models of thermonuclear burning on accreting neutron stars predict different ignition regimes, depending mainly on the mass accretion rate per unit area. For...
Thick discs in galaxies were most likely not accreted
The origin of thick discs in galaxies remains shrouded in mystery. A variety of formation scenarios has been proposed. Here we aim to test one such scenario...
