Spitzer and HHT observations of starless cores: masses and environments (2009)
Stutz, Amelia M., Rieke, George H., Bieging, John H., Balog, Zoltan, Heitsch, Fabian, Kang, Miju, ...
We present Spitzer observations of a sample of 12 starless cores selected to have prominent 24 micron shadows. The Spitzer images show 8 and 24 micron shadows and in some cases 70 micron shadows;...
Muzerolle, James, Flaherty, Kevin, Balog, Zoltan, Furlan, Elise, Smith, Paul S., Allen, Lori, ...
We present multi-epoch Spitzer Space Telescope observations of the transitional disk LRLL 31 in the 2-3 Myr-old star forming region IC 348. Our measurements show remarkable mid-infrared variability...
SPITZER/IRAC-MIPS Survey of NGC2451A and B: Debris Disks at 50-80 million years (2009)
Balog, Zoltan, Kiss, Laszlo L., Vinko, Jozsef, Rieke, G. H., Muzerolle, James, Gaspar, Andras, ...
We present a Spitzer IRAC and MIPS survey of NGC 2451 A and B, two open clusters in the 50-80 Myr age range. We complement these data with extensive ground-based photometry and spectroscopy to...
Young stellar clusters and star formation throughout the Galaxy (2009)
Feigelson, Eric, Adams, Fred, Allen, Lori, Bergin, Edwin, Bally, John, Balog, Zoltan, ...
Most stars are born in rich young stellar clusters (YSCs) embedded in giant molecular clouds. The most massive stars live out their short lives there, profoundly influencing their natal environments...
Currie, Thayne, Kenyon, Scott, Balog, Zoltan, Rieke, George, Bragg, Ann, Bromley, Ben
We describe Spitzer/MIPS observations of the double cluster, h and $\chi$ Persei, covering a $\sim$ 0.6 square-degree area surrounding the cores of both clusters. The data are combined with IRAC and...
Discovery of Gas Accretion Onto Stars in 13 Myr old h and chi Persei (2007)
Currie, Thayne, Kenyon, Scott, Balog, Zoltan, Bragg, Ann, Tokarz, Susan
We report the discovery of accretion disks associated with ~ 13 Myr-old intermediate/low-mass stars in h and chi Persei. Optical spectroscopy of ~ 5000 stars in these clusters and a surrounding halo...
Terrestrial Zone Debris Disk Candidates in h and chi Persei (2007)
Currie, Thayne, Kenyon, Scott J., Rieke, George, Balog, Zoltan, Bromley, Benjamin C.
We analyze 8 sources with strong mid-infrared excesses in the 13 Myr-old double cluster h and chi Persei. New optical spectra and broadband SEDs (0.36-8 mu_m) are consistent with cluster membership....
Spitzer observations of a 24 micron shadow: Bok Globule CB190 (2007)
Stutz, Amelia M., Bieging, John H., Rieke, George H., Shirley, Yancy L., Balog, Zoltan, Gordon, Karl D., ...
We present Spitzer observations of the dark globule CB190 (L771). We observe a roughly circular 24 micron shadow with a 70 arcsec radius. The extinction profile of this shadow matches the profile...
Gordon, Karl D., Engelbracht, Charles W., Fadda, Dario, Stansberry, John, Wachter, Stefanie, Frayer, Dave T., ...
The absolute calibration and characterization of the Multiband Imaging Photometer for Spitzer (MIPS) 70 micron coarse- and fine-scale imaging modes are presented based on over 2.5 years of...
SPITZER/IRAC-MIPS Survey of NGC2244: Protostellar Disk Survival in the Vicinity of Hot Stars (2007)
Balog, Zoltan, Muzerolle, James, Rieke, G. H., Su, Kate Y. L., Young, Eric T.
We present the results from a survey of NGC 2244 from 3.6 to 24 micron with the Spitzer Space Telescope. The 24micron-8micron-3.6micron color composite image of the region shows that the central...
Currie, Thayne, Balog, Zoltan, Kenyon, S. J., Rieke, G., Prato, L., Young, E. T., ...
We describe IRAC 3.6-8 mu_m observations and ground-based near-IR JHKs photometry from Mimir and 2MASS of the massive double cluster h & chi Persei complete to J=15.5 (M ~ 1.3 Msun. Within 25' of the...
Spectroscopic survey of the Galactic open cluster NGC 6871 I. New emission line stars (2002)
Balog, Zoltan, Kenyon, Scott J.
We analyze spectra of 44 emission line stars detected in a low resolution optical spectroscopic survey of the galactic open cluster NGC 6871. The survey of 1217 stars is complete to V = 14.9 and...
