Skrifenn Eth warn Ugens - Tempredh Pur

Tempredh Pur (Absolute Temperature)

Tempredh musurys gans skeul Kelvin: 0 Kelvin = -273.15 ° Celsius

Tempredh Pur yw derivys yn syth dhe nerthedh kynetek dre gehavalyans E = k_B T, mars yw k_B divarenn Boltzmann.

Ytho, tempredh 0 Kelvin a wra omhevelli orth nerthedh mann. 300K = 27°C a wra omhevelli orth nerthedh 0.025 eV

I've started a translation fo selected terms from an astronomical glossary

Braster Pur (Absolute magnitude)

(a) Musur splannyjyom a-berthek sterenn po galaksi.

Braster pur yw styrys avel braster heveladow a'n sterenn po galaksi a'n jeva mar pe ev 32.6 blydhen-golow (10 parsek) a'n nor. An isella braster pur a daklenn, dhe vrassa y splannyjyon a-berthek.
Rag ensample, yma braster pur a +4.83 dhe'n Howl, mes Sirius, neb a'n jeves splannyjyon a-berthek brassa es an Howl, a'n jeves braster pur a +1.43.

I submitted my MSc thesis a little over a week ago! Finally!

Skrifenn Tri warn Ugens - Writing Twenty-three - close to submitting thesis

Feb 18, 2011

I'm close to submitting my MSc thesis. The analysis has really come together well, and I have sorted out (I hope) most of the errors in it. I hope to submit it within a week or two.

So the main point is that the Triangulum Galaxy has interacted with Andromeda, and a load of material has been stripped off the Triangulum (smaller) galaxy as it has gravitationally interacted with the larger Andromeda galaxy. I'm looking at that in a new way, using spectroscopic observations to select stars based on their radial velocity (as determined by their Doppler shift). Then once this selection is made, any differences in composition (what we call metallicity in astronomy) can be measured, although for individual stars in Triangulum galaxy, these measurements are not all that accurate.
