We present 49 new candidate debris disks that were detected around nearby stars with the Spitzer Space Telescope using the Multiband Imaging Photometer (MIPS) at 24 μm (MIPS24) and 70 μm (MIPS70). The survey sample was composed of stars within 25 p

Spitzer and Caltech Submillimeter Observatory images and spectrophotometry of Eridani at wavelengths from 3.5 to 350 μm reveal new details of its bright debris disk. The 350 μm map confirms the presence of a ring at r = 11"-28"(35-90 AU), observed

(abbreviated) We report detection with the Spitzer Space Telescope of cool dust surrounding solar type stars. The observations were performed as part of the Legacy Science Program, ``Formation and Evolution of Planetary Systems'' (FEPS). From the ove

Publikováno v: The Astronomical Journal. 130:1834-1844
Fluxes and upper limits in the wavelength range from 3.6 to 70 microns from the Spitzer Space Telescope are provided for twenty solar-mass Pleiades members. One of these stars shows a probable mid-IR excess and two others have possible excesses, pres

The β Pictoris Disk: Peculiar or Just Young?
Autor: Dana E. Backman, Jack J. Lissauer
Publikováno v: International Astronomical Union Colloquium. 187:309-317
The star β Pictoris is not in itself very remarkable; however, it is surrounded by a dust disk that is much more prominent than any other main sequence star’s disk. The proximity of β Pic and the nearly edge-on viewing geometry of the disk enhanc

Infrared Space ObservatoryPhotometric Search of Main‐Sequence Stars for Vega‐Type Systems
Autor: Dana E. Backman, S. B. Fajardo-Acosta, N. Thakur, Robert E. Stencel
Publikováno v: The Astrophysical Journal. 520:215-222
We obtained 3.6-20 μm photometry of 38 bright [IRAS Fν(12 μm) > 0.7 Jy] main-sequence stars with the Infrared Space Observatory (ISO). Observations were conducted with the ISOPHOT instrument, in the single-pointing photometry mode, through filters

Publikováno v: The Astrophysical Journal. 504:805-820
We have obtained relatively deep imaging in two colors, with limiting magnitudes of V ~ 22.5 and Ic ~ 21, of about one square degree of the Pleiades open cluster. Our primary goal was to identify new candidate brown dwarf members of this ~100 Myr-old

Publikováno v: Astrophysics and Space Science. 255:91-101
Many nearby main sequence stars are surrounded by cool dust radiating strongly in the far-IR. The characteristics of some of the prototype systems will be discussed. The dust is understood to represent debris related to planet formation, and the know
