Sirius (or Sirius A) is amain-sequence starof spectral type early A. Sirius B is one of the largest known white dwarf stars and is 10,000 times dimmer than Sirius. It’s so dim that astronomers couldn’t estimate its mass until 2005 by using data from theHubble Space Telescope. The m...
Sirius is a binary star system made up of two stars, Sirius A and Sirius B. Facts About Sirius:Sirius is a two-star system at a distance of 8.6 light-years from Earth. It consists of the main sequence star Sirius A and a smaller dwarf companion Sirius B. Sirius B is the closest ...
The Sun is an example of a yellow dwarf, also known as a main-sequence star. When a star begins its main sequence life, it is fusing hydrogen to helium within the core. Throughout the life cycle, the core begins to be depleted of hydrogen. As the composition of the core changes, ...
How long (in years) will a 0.10 M_{sun} main sequence star live? (The solar lifetime is 11 billion years). Use the life expectancy of a main sequence star. How does this compare to the current age of the universe (13.7 billion years)? (a) smaller order ...
"The year is 2030. Business is as usual in the isolated research city of Rokumei–that is until several explosions suddenly go off in the nuclear research facility known as "LABO." The city sends in "Sirius," an elite rescue squad, to deal with the situation. But the situation only get...
Intrauterine growth restriction (IUGR) is associated with reduced kidney size at birth, accelerated renal function decline, and increased risk for chronic kidney and cardiovascular diseases in adults. Precise mechanisms underlying fetal programming of ad
TSS-Transcription star site; HRE-Hypoxia response element (ACGTG). (PAS) or Sirius red. In the slices stained with PAS, ten microphotographs (Magnification 400x) were obtained from different renal cortex fields of each kidney and glomerular diameter was quantified in at least 40 glomeruli per ...
Stars with common names such as Sirius, Cursa, Regulus and Nunki are large stars that can be seen in the sky and have been known since the early days of astronomy. They were given star names when astronomy was in its infancy. Most stars with common names will tend to be in the northe...
a Cross sections of hearts from wild type (WT) or Scx null (KO) hearts stained for fibrillar collagen using picrosirius red (BF, bright-field; POL, polarized light), Masson's trichrome or via immunolabeling for total collagen I (red; plus DAPI nuclear staining in blue) revealed matrix ...
Approximately 60 hours later, the bacterial growth was quantified by measuring the bacterial bioluminescence in leaf discs (10 mm in diameter) of infiltrated leaves (one disc per leaf, three discs per plant) using a Sirius FB12 luminometer (Berthold Detection Systems). Bacterial growth rates were...
