New Young Star Candidates in CG4 and Sa101

Autor: Rebull, L. M., Johnson, C. H., Hoette, V., Kim, J. S., Laine, S., Foster, M., Laher, R., Legassie, M., Mallory, C. R., McCarron, K., Sherry, W. H.

The CG4 and Sa101 regions together cover a region of ~0.5 square degree in the vicinity of a "cometary globule" that is part of the Gum Nebula. There are seven previously identified young stars in this region; we have searched for new young stars usi

Main-Seqence Fitting Distance to the sigma Ori Cluster

Autor: Sherry, W. H., Walter, F. M., Wolk, S. J., Adams, N. R.

The sigma Ori cluster is an unbound aggregate of a few hundred young, low-mass stars centered on the multiple system sigma Ori. This cluster is of great interest because it is at an age when roughly half of the stars have lost their protoplanetary di

Simultaneous Multi-Wavelength Observations of Magnetic Activity in Ultracool Dwarfs. II. Mixed Trends in VB10 and LSR1835+32 and the Possible Role of Rotation

Autor: Berger, E., Basri, G., Gizis, J. E., Giampapa, M. S., Rutledge, R. E., Liebert, J., Martin, E., Fleming, T. A., Johns-Krull, C. M., Phan-Bao, N., Sherry, W. H.

[Abridged] As part of our on-going investigation of magnetic activity in ultracool dwarfs we present simultaneous radio, X-ray, UV, and optical observations of LSR1835+32 (M8.5), and simultaneous X-ray and UV observations of VB10 (M8), both with a du

Simultaneous Multi-Wavelength Observations of Magnetic Activity in Ultracool Dwarfs. I. The Complex Behavior of the M8.5 Dwarf TVLM513-46546

Autor: Berger, E., Gizis, J. E., Giampapa, M. S., Rutledge, R. E., Liebert, J., Martin, E., Basri, G., Fleming, T. A., Johns-Krull, C. M., Phan-Bao, N., Sherry, W. H.

[Abridged] We present the first simultaneous radio, X-ray, ultraviolet, and optical spectroscopic observations of the M8.5 dwarf TVLM513-46546, with a duration of 9 hours. These observations are part of a program to study the origin of magnetic activ

Photometric Identification of the low-Mass Population of Orion OB1b I: The sigma Ori Cluster

Autor: Sherry, W. H., Walter, F. M., Wolk, S. J.

Publikováno v: Astron.J.128:2316-2330,2004

We report an optical photometric survey of 0.89 sq. degrees of the Orion OB1b association centered on sigma Ori. This region includes most of the sigma Ori cluster, the highest density region within Orion OB1b. We have developed a statistical procedu
