Spectroscopic survey of Kepler stars. II. FIES/NOT observations of A- and F-type stars
E. Niemczura, M. Polińska, S. J. Murphy +7
We have analysed high-resolution spectra of 28 A and 22 F stars in the Kepler field, observed with the FIES spectrograph at the Nordic Optical Telescope. We provide spectral types,…
The ALMA-PILS survey: First detections of ethylene oxide, acetone and propanal toward the low-mass protostar IRAS 16293-2422
J. M. Lykke, A. Coutens, J. K. Jørgensen +14
One of the open questions in astrochemistry is how complex organic and prebiotic molecules are formed. Aims. Our aim is to start the process of compiling an inventory of oxygen-bea…
The ALMA Protostellar Interferometric Line Survey (PILS): First results from an unbiased submillimeter wavelength line survey of the Class 0 protostellar binary IRAS 16293-2422 with ALMA
J. K. Jørgensen, M. H. D. van der Wiel, A. Coutens +14
The inner regions of the envelopes surrounding young protostars are characterised by a complex chemistry, with prebiotic molecules present on the scales where protoplanetary disks…
The ALMA-PILS survey: First detections of deuterated formamide and deuterated isocyanic acid in the interstellar medium
A. Coutens, J. K. Jørgensen, M. H. D. van der Wiel +15
Formamide (NHCHO) has previously been detected in several star-forming regions and is thought to be a precursor for different prebiotic molecules. Its formation mechanism is st…
Detection of glycolaldehyde towards the solar-type protostar NGC1333 IRAS2A
Audrey Coutens, Magnus V. Persson, Jes K. Jørgensen +2
Glycolaldehyde is a key molecule in the formation of biologically relevant molecules such as ribose. We report its detection with the Plateau de Bure interferometer towards the Cla…
Atmospheric Parameters of 169 F, G, K and M-type Stars in the Kepler Field
J. Molenda-Zakowicz, S. G. Sousa, A. Frasca +15
The asteroseismic and planetary studies, like all research related to stars, need precise and accurate stellar atmospheric parameters as input. We aim at deriving the effective tem…
