HiFLEx – a highly flexible package to reduce cross-dispersed Echelle spectra
(2020-06)
We describe a flexible data reduction package for high resolution cross-dispersed echelle data. This open-source package is developed in Python and includes optional GUIs for most of the steps. It does not require any ...
EXOhSPEC collimator mechanical design
(SPIE, 2019-09-09)
The Exoplanet High-Resolution Spectrograph (EXOhSPEC) is a high-resolution spectrograph for the characterisation of exoplanets with the Thai National Telescope. The folded version of this instrument comprises one triplet ...
EXOhSPEC folded design optimization and performance estimation
(SPIE, 2019-09-09)
The EXOplanet high resolution SPECtrograph (EXOhSPEC) instrument is an echelle spectrograph dedicated to the detection of exoplanets by using the radial velocity method using 2m class telescopes. This spectrograph is ...
Women Scientists Who Made Nuclear Astrophysics
(Springer Nature, 2019-08-20)
Female role models reduce the impact on women of stereotype threat, i.e., of being at risk of conforming to a negative stereotype about one's social, gender, or racial group [1,2]. This can lead women scientists to ...
First light of the VLT planet finder SPHERE IV : Physical and chemical properties of the planets around HR8799
(2016-03-01)
Context. The system of four planets discovered around the intermediate-mass star HR8799 offers a unique opportunity to test planet formation theories at large orbital radii and to probe the physics and chemistry at play ...
Discovery of a brown dwarf companion to the A3V star β Circini
(2015-12-21)
We report the discovery of an L dwarf companion to the A3V star β Circini. VVV J151721.49−585131.5, or β Cir B, was identified in a proper motion and parallax catalogue of the VISTA Variables in the Vía Láctea survey as ...
Hundreds of new cluster candidates in the VISTA Variables in the Vía Láctea survey DR1
(2015-09-18)
Context. VISTA variables in the Vía Láctea is an ESO Public survey dedicated to scanning the bulge and an adjacent portion of the Galactic disk in the fourth quadrant using the VISTA telescope and its near-infrared camera ...
Methane and ammonia in the near-infrared spectra of late-T dwarfs
(2015-06-11)
Analysis of T dwarfs using model atmospheres has been hampered by the absence of reliable line lists for methane and ammonia. Newly computed high-temperature line lists for both of these important molecules are now available, ...
SKYWAY '09: Awareness of the Sky/ The Sky as Awareness - International Light Festival, Impressions and Reflections on the Proceedings
(2009)
Two artists, two astrophysicists, a historian of science, a musician, the Skyway Festival director and the Toruń 2016 director met over two days on the 15th and 16th of August in this beautiful gothic city to discuss the ...
