What Is the Total Deuterium Abundance in the Local Galactic Disk
Analyses of spectra obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, together with spectra from the Copernicus and interstellar medium absorption profile spectrographExpand
A Giant Planet Imaged in the Disk of the Young Star β Pictoris
It is shown that the ~10-million-year-oldβ Pictoris system hosts a massive giant planet, β Pictoris b, located 8 to 15 astronomical units from the star, which confirms that gas giant planets form rapidly within disks and validates the use of disk structures as fingerprints of embedded planets.

A close halo of large transparent grains around extreme red giant stars
Spatially resolved, multiwavelength observations of circumstellar dust shells of three stars on the asymptotic giant branch of the Hertzsprung–Russell diagram show that transparency usually implies insufficient radiative pressure to drive a wind, the radiation field can accelerate these large grains through photon scattering rather than absorption—a plausible mass loss mechanism for lower-amplitude pulsating stars.

CallFUSE Version 3: A Data Reduction Pipeline for the Far Ultraviolet Spectroscopic Explorer
The entire FUSE data set has recently been reprocessed with CalFUSE version 3.2, the latest version of this software, and the format of the resulting calibrated data files are described. Expand
A geometric distance measurement to the Galactic Center black hole with 0.3% uncertainty
We present a 0.16% precise and 0.27% accurate determination of R0, the distance to the Galactic Center. Our measurement uses the star S2 on its 16-year orbit around the massive black hole Sgr A* thatExpand
A Likely Close-in Low-mass Stellar Companion to the Transitional Disk Star HD 142527
With the uniquely high contrast within 0.''1 ({Delta}mag(L') = 5-6.5 mag) available using Sparse Aperture Masking with NACO at Very Large Telescope, we detected asymmetry in the flux from the HerbigExpand
Multiplicity is one of the most fundamental observable properties of massive O-type stars and offers a promising way to discriminate between massive star formation theories. Nevertheless, companionsExpand
The near-infrared spectral energy distribution of β Pictoris b
A gas giant planet has previously been directly seen orbiting at 8-10 AU within the debris disk of the ~12 Myr old star {\beta} Pictoris. The {\beta} Pictoris system offers the rare opportunity toExpand
Oxygen Gas-Phase Abundance Revisited
We present new measurements of the interstellar gas-phase oxygen abundance along the sight lines toward 19 early-type Galactic stars at an average distance of 2.6 kpc. We derive O i column densitiesExpand
Far Ultraviolet Spectroscopic Explorer Survey of the Local Interstellar Medium within 200 Parsecs
We present Far Ultraviolet Spectroscopic Explorer observations of the interstellar gas toward 30 white dwarf stars and one subdwarf (SdO) star. These sight lines probe the Local Bubble (LB) and theExpand
