グリーンカーテンを用いた教室内の温熱環境改善効果の測定を行った。夏季にグリーンカーテンが施された教室とそうでない通常の教室の気温を比較したところ，グリーンカーテンが施された教室の方がわずかではあるが教室内の気温が低下した。また，その遮光効果によって，教室内にある椅子やカーテンの表面温度が低下していることが確認された。このことから，顕著な室内気温の低減にはならないが，総合的に温熱環境を改善できることがわかった。

小惑星2003EH1は軌道要素の類似性から流星群Quadrantidsとの強い関連が指摘されている。Quadrantidsの起源を探るため、枯渇および分裂の2つの放出モデルを立て小惑星2003EH1からテスト粒子を放出しシミュレーションを行った。軌道進化を経て現在のトレイル内に存在するダストのサイズ分布を求め、ダストトレイルのcolor ratioを計算により求めた。赤外線天文衛星AKARI(ASTRO-F: Infrared Imaging Satellite)の全天サーベイによりQuadrantidsのダストトレイルが発見されColor ratioが求められれば、論理的に求めたものとの比較により、Quadrantidsの起源に迫ることができる。, 資料番号: AA0063351003

In this study, we constructed a thermal model of Itokawa considering its shape. And we paid attention to Hayabusa (MUSES-C: Asteroid Sample-return Spacecraft)/XRS (X-Ray Spectrometer) thermometer observations by means of determining the surface conditions of Itokawa. This thermometer was attached to measure the temperature of Hood by which the detectors of XRS were cooled radiatively. Since it was calibrated sufficiently in the thermal vacuum test, we found it is useful to investigate the surface thermal properties of Itokawa. We compared XRS temperature calculated with thermal model with those derived from XRS thermometer observations and made attempt to find the most suitable thermal property of Itokawa., 資料番号: AA0063505021

We observed 2P/Encke in optical wavelength (R-band) for a total of 15 nights from September 9, 2002 to September 9, 2004. The dust trail at five different epochs was detected in the solar phase angle range of 1-26 deg. The typical size of dust particles in the trail is estimated to be about 1 cm according to syndyne curves. It is likely that the scattering phase function of dust particles in the 2P/Encke trail is similar to that of the 2P/Encke nucleus rather than that of dust particles in the tail (approximately 1-10 micrometer)., 資料番号: AA0063350002

Cometary dust trails are composed of large debris ejected from periodic comets. They were first detected in optical wavelength by our group using Kiso 1.05-m Schmidt. The sophisticated data reduction processes as well as the advanced instruments are increasing the total number of trail comets to 15, testifying to the ability of the ground-based observations to achieve the present studies. In this paper, we describe the progress report on the cometary dust trail survey by three ground-based telescopes. In addition, we present the optical color measured under the photometric conditions on Mauna Kea, Hawaii., 資料番号: AA0063350001

月の表面温度は昼夜で激しく異なり、赤道付近では、正午には120度Cまで上昇し、夜間には-180度Cまで下がる。そこで、現有機器の低温耐性はどの程度か、試験した。又、有限要素法の熱解析ソフトであるANSYSを用いて、月面の熱数学モデルを作成し、レゴリスの温度応答を求めると共に、レゴリス上のローバの温度応答を求めた。, The moon surface temperature varies violently, such as 120 C at noon and - 180 C at night. In order to carry out the mission, night survival is the one of the most important issues. Since, super low temperature endurance test was performed to some devises. In addition, using the ANSYS, thermal analysis software of finite element method, temperature response of the lunar regolith and the rover was obtained., 資料番号: AA0047897045

遠赤外線気球望遠鏡(FIRBE)にASTRO-F搭載検出器の試作機を搭載し、オリオン星生成領域を中心とした50平方度の領域を気球観測することに成功した。熱平衡星間ダストが最大強度を放射する遠赤外線帯を波長155μm帯でマッピング観測し、オリオンKL天体、Orion-B領域周辺に有意な信号を検出した。3分角のFIRBE155μmマップは、IRAS100μmマップと同様な空間分布を示した。IRAS100/FIRBE155比から求めたダスト温度、ダスト質量はIRAS60/IRAS100で求められた値に対してダスト温度は10K程度低く、またダスト質量は5〜300倍ほど高い。これは60ミクロン帯におけるダストの非熱放射成分が寄与しておりIRAS60/IRAS100は熱平衡状態にあるダストの物理量を正確に反映しないためである。155μmが卓越したフィラメント状の空間構造は(13)CO分子ガスの空間分布構造と非常によく一致することが明らかになった。, 資料番号: AA0047899148

Evaporation during chondrule melting may have resulted in depletion of volatile elements in chondrules. However, no evidence for a large degree of heavy-isotope enrichment has been reported in chondrules. In order to meet this observed constraint, the rapid heating rate at temperatures in a temperature range from FeS eutectic (1,273 K) to silicate solidus (1,573 K) is required. Numerically simulated was the chondrule formation with shock-wave heating model including the radiative transfer among dust particles. It has been found that if the preshock region is optically thin for the thermal continuum emission from dust particles, the shock-wave heating mechanism meets the high heating rate constraint, because the dust thermal emission does not keep the dust particles high temperature for a long time in the preshock region. In such a case, the dust particles are abruptly heated by the gas drag heating behind the shock front., 資料番号: AA0047898011

Thermal stability as well as optical properties of submicron-period microstructures on W surfaces has been investigated for developing new radiation control devices in space. Numerical calculations based on rigorous coupled-wave analysis are performed to determine the structural profile of gratings with good spectral selectivity. According to the determined parameters, two-dimensional W gratings composed of rectangular microcavities with the period of 1.0 micrometer are fabricated on single crystalline and polycrystalline W substrates. The grating shows a strong emission peak, which can be explained by the confined modes inside the cavities. The grating with 200 nm wall thickness made from a single crystalline W shows very high thermal stability over 1,400 K, while the polycrystalline grating is deformed at a high temperature because of the grain growth. It is confirmed that the thermal stability has been improved by using single crystalline substrates., 資料番号: AA0045438044

We mapped the distribution of H3(+) emissions in Jupiter's polar regions utilizing 3.4-micrometer images acquired with ProtoCAM at the NASA IRTF (Infrared Telescope Facility). A sequence of image mosaics was used to constrain the parameters of an emission source model. A generalized inverse methodology, applied to individual pixel intensities in the sequence of auroral images, is used to constrain the model parameters. A combination of the System-3 fixed anomaly (equatorward of the auroral oval) plus the local-time fixed anomaly (poleward) was found to simulate the emission intensities in both aurorae consistently well. Weaker H3(+) emissions are found both poleward and equatorward of the oval, the latter extending approximately to the footprint of the Io torus at most longitudes. System-3 anomalies are tentatively identified at longitudes where the local magnetic field strength is less than that at the conjugate point., 資料番号: AA0063352037
