An automotive company’s goal is to design and manufacture vehicles that meet the needs and expectations of its customers. Laboratory (lab) testing is a critical step in developing vehicle components or systems. It allows the design engineer to evaluate the design early in the product development process. Establishing a good lab-test minimum-life requirement(More)

Q1 FS CMa stars form a group of objects with the B[e] phenomenon that were previously known as unclassified B[e] stars or B[e] stars with warm dust (B[e]WD) until recently. They exhibit strong emission-line spectra and strong IR excesses, most likely due to recently formed circumstellar dust. These properties have been suggested to be due to ongoing or(More)
Aims. We present the results of high-resolution optical spectroscopy, low-resolution near-IR spectroscopy and near-infrared speckle interferometry of the massive young stellar object candidate V645 Cyg, acquired to refine its fundamental parameters and the properties of its circumstellar envelope. Methods. Speckle interferometry in the Hand K-bands and an(More)

We present 0.35 to 2.5 μm spectra of the south and northwest filaments in the reflection nebula NGC 7023. These spectra were used to test the theory of Seahra & Duley that carbon nanoparticles are responsible for Extended Red Emission (ERE). Our spectra fail to show their predicted second emission band at 1.0 μm even though both filaments exhibit strong(More)
We present the results of optical and near-IR spectroscopic and broadband multicolour photometric observations of the emission-line object V669 Cep. We find evidence that it contains a hot, low luminosity, B4– B6 star and a cool companion (most likely late-type giant). Significant variations of the Hα line strength are detected on a timescale of months. The(More)
We report 0.8–2.5 m spectrophotometry of CI Aquilae at eight epochs between 2000 May 9 and 2001 June 2 UT, corresponding to approximately 3 and 391 days after peak brightness. Near peak brightness, the spectra showed emission lines that were characteristic of a low-excitation, nitrogen-rich shell. Within a few weeks, the spectra began to show higher(More)
We describe a concept for a new imaging spectrometer operating in the mid-wave and long-wave infrared. The instrument would be proposed as an upgrade to The Aerospace Corporation’s Broadband Array Spectrometer System (BASS), a 2.9-14 micron sensor currently in use on the Advanced Electro-Optical System (AEOS) 3.67 meter telescope. The primary tasks of the(More)
