Publications of the Astronomical Society of Japan, Apr 10, 2024Abstract The Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aerospace Exploration Agency. JASMINE has two main science goals. One is Galactic archaeology with a Galactic Center survey, which aims to reveal the Milky Way’s central core structure and formation history from Gaia-level (∼25 ${\mu} $as) astrometry in the near-infrared (NIR) Hw band (1.0–1.6 ${\mu} $m). The other is an exoplanet survey, which aims to discover transiting Earth-like exoplanets in the habitable zone from NIR time-series photometry of M dwarfs when the Galactic Center is not accessible. We introduce the mission, review many science objectives, and present the instrument concept. JASMINE will be the first dedicated NIR astrometry space mission and provide precise astrometric information on the stars in the Galactic Center, taking advantage of the significantly lower extinction in the NIR. The precise astrometry is obtained by taking many short-exposure images. Hence, the JASMINE Galactic Center survey data will be valuable for studies of exoplanet transits, asteroseismology, variable stars, and microlensing studies, including discovery of (intermediate-mass) black holes. We highlight a swath of such potential science, and also describe synergies with other missions.

Abstracts for fall meeting of the Japanese Society for Planetary Science, 2005f 121-121, 2005Light scattering properties of cometary dust in coma have been investigated well. However, that of dust particles in cometary dust trail have not been examined yet because of its faintness in optical wavelength. We observed 2P/Encke for a total of 15 nights over the period of 2002 September 9 - 2004 September 9. The observations were carried out using 2k CCD camera mounted on Kiso 1.05-m Schmidt telescope and 8k mosaic CCD camera mounted on University of Hawaii 2.24-m telescope. All data were taken with R-band filter. The 2P/Encke trail was detected at 5 different epochs. The range of the heliocentric distance, the geocentric distance, and the solar phase angle of 2P/Encke, where the trail was detected, are 1.78-3.98 AU, 0.94-2.97 AU, and 1-26 degree, respectively. According to fitting of the syndyne curves, it was found that the trail is composed of particles whose size is larger than approximately 1 cm. It is likely that the scattering phase function of 2P/Encke trail particles is similar to that of nucleus of comet rather than that of dust particles in coma.

The Institute of Space and Astronautical Science report. S.P., 15 23-27, Mar, 2003The faint glow at the direction of the dust trail of comet 55P/Tempel-Tuttlewas discovered during the Leonid meteor shower in 1998 (ΔMA = 0.136) by the photometricobservations at Mauna Kea, Hawaii (Nakamura et al. (2000)). This is considered as the scatteredsunlight by the sub-millimeter size dust particles located along the orbit of 55P/Tempel-Tuttle.To examine the orbital distribution of the dust particles, we observed the direction of the dusttrail on 2001 November 19 (ΔMA = O.705), at Akeno Observatory (138d30m(E), 35d47m(N),900m, Institute for Cosmic Ray Research, University of Tokyo, Japan) . The instruments were thesame one as Nakarnura et al. (2000) used. From our data, there is no prominent evidence detectedat that direction. Based on these two data obtained in 1998 and 2001, we discuss the spatialdistribution of the dust material observed as the dust tube in visible wavelength.

Abstracts for fall meeting of the Japanese Society for Planetary Science, 2003 88-88, 2003We have succeeded in detecting a dust trail along the orbit of the short-period comet 81P/Wild2 , the target of the Stardust mission, which will fly by 81P/Wild2 in 2004 January. Based on our observation, it is likely that the trail is composed of dust particles with a diameter of about 1mm. During the flyby phase of the Stardust spacecraft, the spacecraft will come across the impacts of such large dust particles along the comet's orbit. In this study , we examine the impact fluence and impact velocity of the dust particles onto the Stardust spacecraft.

Abstracts Fall Meeting of the Japanese Society for Planetary Sciences, 2001 91-91, Oct 6, 2001Zodiacal light is a scattered sunlight by interplanetary dust. We have developed a new instruments, WIZARD(Wide-field Imager of Zodiacal light with ARray Detector), for the observations of not only widespread faint, zodiacal light, but also NO2 airglow. We have obtained the first images by WIZARD at Manua Kea (Hawaii, 4200m) on March, 2001, under the collaboration of SUBARU. In this work, we report the detail specification of WIZARD.
