Talk:Chandrasekhar limit

Inconsistency between solar mass value and kg value in the lead

The lead states the Chandrasekhar limit is "about 1.44 M☉ (2.765×10^30 kg)." These two figures are inconsistent with each other.

Using the standard solar mass M☉ = 1.989×10^30 kg:

$1.44\times 1.989\times 10^{30}\text{kg}=2.864\times 10^{30}\text{kg}$

not 2.765×10^30 kg as stated. The value 2.765×10^30 kg corresponds to:

$\frac{2.765\times 10^{30}}{1.989\times 10^{30}}\approx 1.390M_{\odot }$

So the article's kg figure (2.765×10^30 kg) matches ~1.39 M_☉, while the article's M_☉ figure (1.44 M_☉) would correspond to ~2.864×10^30 kg. One of the two must be corrected — either change the solar-masses figure to ~1.39 M_☉ (which is in fact another commonly quoted value for the limit), or change the kg value to 2.864×10^30 kg to match 1.44 M_☉.
