IRAM and Gaia views of multi-episodic star formation in IC1396A: The origin and dynamics of the Class 0 protostar at the edge of an HII region
Aurora Sicilia-Aguilar, Nimesh Patel, Min Fang +3
(Abridged) IC1396A is a cometary globule containing the Class 0 source IC1396A-PACS-1. We use IRAM 30m and Gaia DR2 data to explore the star-formation history of IC1396A and invest…
High-resolution spectroscopy of Boyajian's star during optical dimming events
M. J. Martínez González, C. González-Fernández, A. Asensio Ramos +13
Boyajian's star is an apparently normal main sequence F-type star with a very unusual light curve. The dipping activity of the star, discovered during the Kepler mission, presents…
Warm dust surface chemistry. H2 and HD formation
W. F. Thi, S. Hocuk, I. Kamp +4
Molecular hydrogen (H2) is the main constituent of the gas in the planet-forming disks that surround many PMS stars. H2 can be incorporated in the atmosphere of the giant planets.…
Simultaneous analysis of SDSS spectra and GALEX photometry with STARLIGHT: Method and early results
Ariel Werle, Roberto Cid Fernandes, Natalia Vale Asari +4
We combine data from the Sloan Digital Sky Survey and the Galaxy Evolution Explorer to simultaneously analyze optical spectra and ultraviolet photometry of 231643 galaxies with the…
Warm dust surface chemistry in protoplanetary disks. Formation of phyllosilicates
W. F. Thi, S. Hocuk, I. Kamp +5
The origin of the reservoirs of water on Earth is debated. The Earth's crust may contain at least three times more water than the oceans. This crust water is found in the form of p…
Exoplanet Clouds
Christiane Helling
Clouds also form in atmospheres of planets that orbit other stars than our Sun, in so-called extrasolar planets or exoplanets. Exoplanet atmospheres can be chemically extremely ric…
