The physics and modes of star cluster formation: observations
Charles J. Lada
Stellar clusters are born in cold and dusty molecular clouds and the youngest clusters are embedded to various degrees in dusty dark molecular material. Such embedded clusters can…
A Spitzer Census of Star Formation Activity in the Pipe Nebula
Jan Forbrich, Charles J. Lada, August A. Muench +2
The Pipe Nebula, a large nearby molecular cloud lacks obvious signposts of star formation in all but one of more than 130 dust extinction cores that have been identified within it.…
High Resolution Near-Infrared Survey of the Pipe Nebula I: A Deep Infrared Extinction Map of Barnard 59
Carlos G. Román-Zúñiga, Charles J. Lada, João F. Alves
We present our analysis of a fully sampled, high resolution dust extinction map of the Barnard 59 complex in the Pipe Nebula. The map was constructed with the infrared color excess…
The California Molecular Cloud
Charles J. Lada, Marco Lombardi, Joao F. Alves
We present an analysis of wide-field infrared extinction maps of a region in Perseus just north of the Taurus-Auriga dark cloud complex. From this analysis we have identified a mas…
IRS Characterization of a Debris Disk around an M-type star in NGC2547
Paula S. Teixeira, Charles J. Lada, Kenneth Wood +2
We present 5 to 15 micron Spitzer Infrared Spectrograph (IRS) low resolution spectral data of a candidate debris disk around an M4.5 star identified as a likely member of the ~40 M…
Dense cores in the Pipe Nebula: An improved core mass function
J. M. Rathborne, C. J. Lada, A. A. Muench +3
In this paper we derive an improved core mass function (CMF) for the Pipe Nebula from a detailed comparison between measurements of visual extinction and molecular-line emission. W…
The Last Gasp of Gas Giant Planet Formation: A Spitzer Study of the 5 Myr-old Cluster NGC 2362
Thayne Currie, Charles J. Lada, Peter Plavchan +3
(Abridged) We describe Spitzer IRAC and MIPS observations of the populous, 5 Myr-old open cluster NGC 2362. Early/intermediate-type confirmed/candidate cluster members either have…
On the fidelity of the core mass functions derived from dust column density data
J. Kainulainen, C. J. Lada, J. M. Rathborne +1
Aims: We examine the recoverability and completeness limits of the dense core mass functions (CMFs) derived for a molecular cloud using extinction data and a core identification sc…
The Diskionary: A Glossary of Terms Commonly Used for Disks and Related Objects, First Edition
Neal Evans, Nuria Calvet, Lucas Cieza +6
Based on a panel discussion at the meeting "New Light on Young Stars: Spitzer's View of Circumstellar Disks", we provide some definitions of common usage of terms describing disks…
