Surprising detection of an equatorial dust lane on the AGB star IRC+10216

S. V. Jeffers, M. Min, L. B. F. M. Waters +6

Understanding the formation of planetary nebulae remains elusive because in the preceding asymtotic giant branch (AGB) phase these stars are heavily enshrouded in an optically thic…

Observations of water with Herschel/HIFI toward the high-mass protostar AFGL 2591

Y. Choi, F. F. S. van der Tak, E. F. van Dishoeck +2

Water is a sensitive tracer of physical conditions in star-forming regions because of its large abundance variations between hot and cold regions. We use spectrally resolved observ…

ZFOURGE/CANDELS: On the Evolution of M* Galaxy Progenitors from z=3 to 0.5

Casey Papovich, I. Labbé, R. Quadri +38

Galaxies with stellar masses near M* contain the majority of stellar mass in the universe, and are therefore of special interest in the study of galaxy evolution. The Milky Way (MW…

Erosion and the limits to planetesimal growth

Sebastiaan Krijt, Chris W. Ormel, Carsten Dominik +1

The coagulation of microscopic dust into planetesimals is the first step towards planet formation. The size and shape of the growing aggregates determine the efficiency of this ear…
