The metallicity of CM Draconis
We compare observations of the eclipsing binary system CM Draconis (hereafter CM Dra) with synthetic spectra computed using the stellar atmosphere code PHOENIX. High-resolution infrared spectroscopic observations of six 0.05-mm-wide regions between 1.51 and 2.45mm, combined with previous work, particularly CM Dra’s accurately known surface gravity, enable us to estimate its metallicity using de...
متن کاملA search for Jovian-mass planets around CM Draconis using eclipse minima timing
For the eclipsing binary system CM Draconis, eclipse minimum times have been monitored with high precision between 1994 and 1999. Periodic deviations of minimum times from a linear ephemeris may indicate the presence of an orbiting third body. Individual measurements of 41 eclipse minimum times result in a standard deviation from linear ephemeris of 5.74 seconds. A power spectral analysis of th...
متن کاملFrom CM Draconis to the Crowded Field BW3: Aspects of the Search for Extrasolar Planets Around Small Eclipsing Binaries
We review some apsects of the search for extrasolar planets around small-mass short-period eclipsing binaries, including lessons from the extensive search around CM Draconis (over 1,000 hours), and the extention of the search to small eclipsing binaries in the crowded field Baade’s Window 3 (BW3) in the Galactic plane. In addition to being of intrinsic interest to planet formation studies, due ...
متن کاملDraconis: Rethinking the Storage Stack
High performance storage systems like file systems, databases and persistent key value stores have very high storage I/O requirements. To maximize the efficiency of disk I/O, these systems usually make certain assumptions about the performance characteristics of the underlying storage medium, and design their disk read/write patterns accordingly. Some of the common assumptions include: sequenti...
متن کاملROTATIONAL ASSIGNMENT OF NEW BANDS IN THE NO , EXCITATION SPECTRUM IN THE SPECTRAL RANGE OF 15600 cm TO 15633 cm
Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra ...
