GO 11572: Characterizing Atmospheric Sodium in the Transiting hot-Jupiter HD189733b
An artist's impression of the hot Jupiter circling a solar-type star
|
HD 198733 is a 7th magnitude G5 dwarf that lies at a distance of ~20 parsecs from the Sun, in the direction of the constellation of Vulpecula. Like many other nearby solar-type stars, HD 189733 has an associated planetary system, including a hot Jupiter, a ~1.15 MJ gas giant with an orbital period of 2.12 days. Most significantly, that inner planet transits the central star, making HD 189733 the closest transiting system found so far. Transiting systems offer a potential gold-mine for extrasolar planetary studies, since not only is the orbital inclination well defined, but the diameter (and hence the average density) is directly measureable form the eclipse depth, while the atmospheric composition can be probed through line absorption or re-radiated thermal flux. The results from these measurments can be used to test, and improve, theoretical models of extrasolar planets. These observations are best done from space (indeed, the only successful atmospheric observations to date have been with HST and Spitzer). HD 189733 has already been studied extensively with HST using the grism on the Advanced Camera for Surveys and, at near-infrared wavelengths, NICMOS. However, it's discovery postdated the STIS electronic failure, so it has never been studied at even moderate spectral resolution. The present observations will use the G750M grating on STIS to monitor three transits, and the data will be analysed for the presence of enhanced sodium absorption, as previously detected in the original bright transiting planet, HD 209458b. |
GO 11697: Proper Motion Survey of Classical and SDSS Local Group Dwarf Galaxies
The low-mass dwarf galaxy, Leo II
|
The Milky Way, m31 and M33 are the three largest galaxies in the Local Group. The system, however, includes more than 25 other members, the majority being dwarf spheroidal galaxies that are satellites of either M31 or the Milky Way. Those galaxies have old, evolved stellar populations, and even the most prominent have masses that are less than a few x 107 MSun, or 10-4 that of the Milky Way. All of these galaxies are moving in the potential set by the overall Local Group system, but dominated by M31 and the Milky Way. Determining full space motions for the dwarfs therefore provide a means of constraining that potential. Even thought the galaxies, and their brightest stellar constituents, are faint, measuring radial velocity is a relatively straightforward procedure. Deriving tangential motions is not, since the typical proper motions of these systems are a few mas/year at best. The present proposal aims to capitalise on the exceptional resolution and high stability of HST to address this issue. WFC3 will target 7 dwarf galaxies, imaging fields that are centred on a background QSO. That QSO serves as a reference point for measurement of the transverse motion of stars in the foreground dwarf galaxy. |
GO 11727: UV spectroscopy of Local Lyman Break Galaxy Analogs: New Clues to Galaxy Formation in the Early Universe
Mosaic of HST images of M82, the best-known starburst galaxy
|
Current Big Bang cosmological models predict that the universe should have undergone a global re-ionisation at redshifts between 6 and 20. The first generation of stars is generally tapped as the most likely source of the ionising radiation, perhaps enhanced through merger-stimulated starbursts. Candidate galaxies at high redshift have been identified by searching for "dropouts": objects where the flux decreases significantly in the photometric passband associated with the Lyman break at a particular redshift. Deep observations with WFC3 have extended coverage to redshifts 7 and 8. However, detailed observations of such systems are not yet possible. Consequently, there is great interest in identifying galaxies at lower redshifts that could serve as analogues for the z>6 systems. Over the last few years, the Galaxy Evolution Explorer (GALEX) has proved an important new tool in identifying "Lyman Break Analogues". GALEX has conducted an all-sky survey at ultraviolet wavelengths, and has uncovered sigificant numbers of UV luminous galaxies at low and moderate redshifts. Many galaxies are starbursts, undergoing substantial outbursts of star formation. These galaxies have been categorised as "compact UV luminous galaxies" (UVLGs), and appear to be undergoing small-scale mergers, leading to extensive dissipation and vigorous star formation. These galaxies have extensive prior HST observations at optical and near-UV wavelengths. The present program will add COS Far-UV observations, to fully characterise the spectral energy distributions. |
