通过消光校正H得到的恒星形成率（SFRs）与密集气体的形成率（通过ASTE望远镜观测到的附近星系中心的12 CO （J= 3-2）发射来追踪）。我们发现，虽然许多观测到的位置是多尘的，因此在H处被大量吸收，但heSFR与稠密气体以施密特定律的形式表现出惊人的相关性，其指数为1.0。还比较了12 CO （J= 1-0）追踪的气体与H消光校正的应用之间的相关性。我们发现稠密的气体产生a
Star formation rates (SFRs) obtained via extinction-corrected H˛ are compared to dense gas, as traced by 12 CO ( J= 3–2) emission at the centers of nearby galaxies, observed with the ASTE telescope. It is found that, although many of the observed positions are dusty, and therefore heavily absorbed at H˛ ,t heSFR shows a striking correlation with dense gas in the form of the Schmidt law with an inde xo f 1.0. The correlation is also compared between gas traced by 12 CO ( J= 1–0) and the application of an H˛ extinction correction. We fin dt hat dense gas produces a
