Warm water deuterium fractionation in IRAS 16293-2422 - The high-resolution ALMA and SMA view
Magnus V. Persson, Jes K. Jørgensen, Ewine F. van Dishoeck
Measuring the water deuterium fractionation in the inner warm regions of low-mass protostars has so far been hampered by poor angular resolution obtainable with single-dish ground-…
Strong irradiation of protostellar cores in Corona Australis
J. E. Lindberg, J. K. Jørgensen
The importance of the physical environment in the evolution of newly formed low-mass stars remains an open question. In particular, radiation from nearby more massive stars may aff…
Fundamental properties of the Population II fiducial stars HD 122563 and Gmb 1830 from CHARA interferometric observations
O. L. Creevey, F. Thévenin, T. S. Boyajian +17
We have determined the angular diameters of two metal-poor stars, HD 122563 and Gmb 1830, using CHARA and Palomar Testbed Interferometer observations. For the giant star HD 122563,…
The Transiting System GJ1214: High-Precision Defocused Transit Observations and a Search for Evidence of Transit Timing Variation
K. B. W. Harpsøe, S. Hardis, T. C. Hinse +37
Aims: We present 11 high-precision photometric transit observations of the transiting super-Earth planet GJ1214b. Combining these data with observations from other authors, we inve…
The Transiting Circumbinary Planets Kepler-34 and Kepler-35
William F. Welsh, Jerome A. Orosz, Joshua A. Carter +43
Most Sun-like stars in the Galaxy reside in gravitationally-bound pairs of stars called "binary stars". While long anticipated, the existence of a "circumbinary planet" orbiting su…
Halo abundances and shear in void models
David Alonso, Juan García-Bellido, Troels Haugboelle +1
We study the non-linear gravitational collapse of dark matter into halos through numerical N-body simulations of Lemaitre-Tolman-Bondi void models. We extend the halo mass function…
