Temporal and spatial variability of clouds and related aerosols (2009)
Anderson, T. L., Ackerman, A., Hartmann, D. L., Isaak, G. A., Kinne, S., Masunaga, H., ...
A comparison of chemistry and dust cloud formation in ultracool dwarf model atmospheres (2008)
Helling, Ch., Ackerman, A., Allard, F., Dehn, M., Hauschildt, P., Homeier, D., ...
The atmospheres of substellar objects contain clouds of oxides, iron, silicates, and other refractory condensates. Water clouds are expected in the coolest objects. The opacity of these `dust' clouds...
Comparison of cloud models for Brown Dwarfs (2007)
Helling, Ch., Ackerman, A., Allard, F., Dehn, M., Hauschildt, P., Homeier, D., ...
A test case comparison is presented for different dust cloud model approaches applied in brown dwarfs and giant gas planets. We aim to achieve more transparency in evaluating the uncertainty inherent...
Clouds and Clearings in the Atmospheres of the L and T Dwarfs (2002)
Marley, M. S., Ackerman, A., Burgasser, A. J., Saumon, D., Lodders, K., Freedman, R.
A sophisticated approach to condensate opacity is required to properly model the atmospheres of L and T dwarfs. Here we review different models for the treatment of condensates in brown dwarf...
The contribution of syngeneic bone marrow and thymus cell populations obtained from normal and cortisone-treated donor mice for reconstitution of delayed hypersensitivity to methylated human serum...
Fate of Surviving Low-birth-weight Infants with Coagulation Deficiencies on the First Day of Life
Bryant, G. M., Gray, O. P., Fraser, A. J., Ackerman, A.
Fifty-two surviving low-birth-weight infants who had low Thrombotest (Owren) results on the first day, together with the same number of matched controls with higher Thrombotest results, were examined...
