The Corona of the Young Solar Analog Ek Draconis
First coronal microwave and new soft X-ray observations (complementary to those reported by Dorren et al. 1995) of the very active, near-Zero-Age Main-Sequence (ZAMS) dG0e star EK Dra = HD 129333 show that this analog of the young Sun is more luminous in both emissions than most single M-dwarf are stars. Variations in the 8.4 GHz ux include the optically determined rotation period of 2.7 days. ...
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 کاملThe 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 کامل(gk Draconis and V1094 Tauri)
The two stars that form the subject of this paper are both short-period double-lined eclipsing binaries. They have non-circular orbits despite their short periods, both of which are very close to integral numbers of sidereal days (10.0015 and 9.0127 sidereal days respectively), making it difficult to achieve uniform phase coverage of the orbits from a single site in the short term. Although the...
متن کاملEffects of Sanguis Draconis on Perforator Flap Survival in Rats.
Sanguis draconis, a resin known to improve blood circulation, relieve pain, stimulate tissue regeneration, and heal wounds, is widely used in clinical practice. In this study, we prepared an ethanol extract of sanguis draconis (EESD) containing 75.08 mg/g of dracorhodin. The experiment was carried out on 20 rats that were divided into two groups, a control group (n = 10) and an EESD group (n = ...
