Early Spectroscopy and Photometry of the New Outburst of V1647 Ori
V1647 Ori is a young eruptive variable star, illuminating a variable reflection nebula (McNeil's Nebula). The previous outburst of the star between 2004 January and 2005 October has been extensively documented in the literature (e.g. Briceño et al. 2004, Ojha et al. 2006, Acosta-Pulido et al. 2007, Fedele et al. 2007). Optical, near-, and mid-infrared observations of the star during the quiesce...
متن کاملX-ray Spectral Variability during an Outburst in V1118 Ori
We present results from a multi-wavelength campaign to monitor the 2005 outburst of the low-mass young star V1118 Ori. Although our campaign covers the X-ray, optical, infrared, and radio regimes, we focus in this Letter on the properties of the X-ray emission in V1118 Ori during the first few months after the optical outburst. Chandra and XMM-Newton detected V1118 Ori at three epochs in early ...
متن کاملPost-outburst Observations of V1647 Orionis: Detection of a Brief Warm Molecular Outflow
We present new observations of the fundamental rovibrational CO spectrum of V1647 Ori, the young star whose recent outburst illuminated McNeil’s Nebula. Previous spectra, acquired during outburst in 2004 February and July, had shown the CO emission lines to be broad and centrally peaked, similar to the CO spectrum of a typical classical T Tauri star. In this Letter, we present CO spectra acquir...

We present new observations of the fundamental ro-vibrational CO spectrum of V1647 Ori, the young star whose recent outburst illuminated McNeil’s Nebula. Previous spectra, acquired during outburst in 2004 February and July, had shown the CO emission lines to be broad and centrally peaked—similar to the CO spectrum of a typical classical T Tauri star. In this paper, we present CO spectra acquire...
متن کاملInfrared Spectroscopy of U Equulei ’ s Warm Circumstellar Gas
Medium and high resolution spectroscopy of U Equulei from 1 to 4 µm during 1997-2003 has revealed information about its unusual circumstellar envelope, observed previously at optical and radio wavelengths. Strong absorption bands of H 2 O and of CO dominate the 1–4 µm spectrum. The gas has a mean temperature of 600 K and 12 C/ 13 C≤10. The CO 2-0 line profiles and velocities imply no net ejecti...
