Sentence examples for by the main sequence from inspiring English sources

The main sequence ends at about spectral type G, however, and does not extend up through the A, B, and O spectral types, though occasionally a few such stars are found in the region normally occupied by the main sequence.

Although it is well understood how the stereotyped saccades are generated by the brain, it is not understood why they are so stereotyped and why they have the precise properties as described by the main sequence.

Although in normal behavior, the duration is given by the main sequence, we will consider a range of hypothetical durations and for each duration calculate the trajectory that produces the smallest variance in saccade endpoints, averaged over a 50 ms post-movement fixation period [13].

Annotation is provided in three distinct formats: Feature Table (FT), extended FT and Generic Feature Format (GFF) 3. FT is the annotation format and vocabulary terms adopted by the main sequence repositories (DDBJ/EMBL/GenBank).

By knowing the main sequence lifespan of stars at this point, it becomes possible to estimate the age of the cluster.

Sequencing wheat chromosome 5A by 454 revealed the main sequence features of this chromosome, including candidate miRNA precursors, and enabled the production of a virtual gene order based on synteny with other phylogenetically related species (Vitulo et al. 2011).

Seed alignments, which serve as Bayesian priors to help define each sequence set, were obtained by selecting from the main sequence alignment a few well-characterized proteins belonging to each of the major P-loop GTPase subgroups and to each of the largest Arf/Arl subfamilies.

The spectral shape of the radiation emitted by Population III stars on the main sequence may be derived by combining stellar structure calculations with detailed LTE and non-LTE model atmospheres (Cojazzi et al. 2000; Tumlinson and Shull 2000; Bromm et al. 2001b; Schaerer 2002, 2003).

The giants are separated from the main sequence by a gap named for Hertzsprung, who in 1911 became the first to recognize the difference between main-sequence and giant stars.

The mechanism by which the SC incorporates the main sequence, and hence acts as a nonlinear vectorial pulse generator, appears to be by a gradient in the burst properties across the motor map, from brief and intense in the rostral zone, to less intense and of longer duration in the caudal zone.

By the time the star reaches the main sequence, it is still chemically homogeneous.
