Research of low-carbon transition path of star hotels--A case study of Guilin
SHS Web of Conferences, 2016 A general trend of the world economic development is the low-carbon economic transition. With a wide influencing range and rapid development, the hotel industry has prominent problems in the energy con-sumption, resources occupancy and environmental ...

Thermal design and analysis of high power star sensors
Case Studies in Thermal Engineering, 2015 The requirement for the temperature stability is very high in the star sensors as the high precision needs for the altitude information. Thermal design and analysis thus is important for the high power star sensors and their supporters.

HIFI detection of hydrogen fluoride in the carbon star envelope IRC +10216 [PDF]
, 2011 We report the detection of emission in the J = 1−0 rotational transition of hydrogen fluoride (HF), together with observations of the J = 1−0 to J = 3−2 rotational lines of H35Cl and H37Cl, towards the envelope of the carbon star IRC +10216.

Tracing the origin of neutron-capture elements in the metalpoor star HE 1244-3036 [PDF]
EPJ Web of ConferencesWe present results from a detailed abundance analysis of a star HE 1244-3036, based on a high resolution (R ∼ 50000) SUBARU/HDS spectrum. The wavelength coverage is from 3510 to 5310 Å. Our estimated metallicity [Fe/H] ∼ −2.5 and carbon abundance ([C/Fe]

Carbon Stars and Nucleosynthesis in Galaxies [PDF]
Symposium - International Astronomical Union, 2000 The role of carbon stars in the build-up of chemical elements in galaxies is discussed on the basis of stellar evolution calculations and estimated stellar yields, abundance analyses of AGB stars, galactic-evolution models and abundance trends among solar-type disk stars.

CD -24_17504 revisited: a new comprehensive element abundance analysis [PDF]
, 2015 With [Fe/H] ~ -3.3, CD -24_17504 is a canonical metal-poor main sequence turn-off star. Though it has appeared in numerous literature studies, the most comprehensive abundance analysis for the star based on high resolution, high signal-to-noise spectra ...

The absolute magnitudes of carbon stars - Carbon stars in binary systems
The Astrophysical Journal, 1975 Absolute visual magnitudes have been determined for carbon stars belonging to binary systems. These range from about 0 to brighter than -4, with a mean value of -2.3 for N stars. Bolometric corrections are deduced, giving bolometric absolute magnitudes in the range -4 to -8.

Warm water vapour in the sooty outflow from a luminous carbon star [PDF]
Nature, 2010 The detection of circumstellar water vapour around the ageing carbon star IRC +10216 challenged the current understanding of chemistry in old stars, because water was predicted to be almost absent in carbon-rich stars.
