new fine structure cooling rate [PDF]
Geophysical Research Letters, 1976 One of the dominant electron cooling processes in the ionosphere is caused by electron impact induced fine structure transitions among the ground state levels of atomic oxygen. This fine structure cooling rate is based on theoretical cross sections. Recent advances in the numerical cross section determinations to include polarization effects and more ...

An Empirical Measure of the Rate of White Dwarf Cooling in 47 Tucanae
, 2012 We present an empirical determination of the white dwarf cooling sequence in the globular cluster 47 Tucanae. Using spectral models, we determine temperatures for 887 objects from Wide Field Camera 3 data, as well as 292 objects from data taken with the ...

Cooling a micro-mechanical resonator by quantum back-action from a noisy qubit [PDF]
, 2009 We study the role of qubit dephasing in cooling a mechanical resonator by quantum back-action. With a superconducting flux qubit as a specific example, we show that ground-state cooling of a mechanical resonator can only be realized if the qubit ...

Effectiveness of hand cooling and a cooling jacket on post‐exercise cooling rates in hyperthermic athletes [PDF]
European Journal of Sport Science, 2018 AbstractThis study compared the effects of a hand cooling glove (∼16°C water temperature; subatmospheric pressure of −40 mmHg) and a cooling jacket (CJ) on post‐exercise cooling rates (gastrointestinal core temperature, Tc; skin temperature, Tsk) and cognitive performance (the Stroop Colour–Word test). Twelve male athletes performed four trials (within

Critical cooling rate and thermal stability of Zr–Ti–Cu–Ni–Be alloys [PDF]
, 2001 The critical cooling rate as well as the thermal stability are measured for a series of alloys in the Zr–Ti–Cu–Ni–Be system. Upon cooling from the molten state with different rates, alloys with compositions ranging along a tie line from (Zr70Ti30)55 ...

Constraining the neutrino magnetic dipole moment from white dwarf pulsations [PDF]
, 2014 Pulsating white dwarf stars can be used as astrophysical laboratories to constrain the properties of weakly interacting particles. Comparing the cooling rates of these stars with the expected values from theoretical models allows us to search for ...
