The optical high-resolution spectral archive of the HERMES spectrograph mounted on the 1.2m Mercator telescope
Hans Van Winckel, Saskia Prins, Gert Raskin +13
Context. The HERMES spectrograph is a high-resolution, fibre-fed optical spectrograph of the 1.2m Mercator telescope operated from the Roque de los Muchachos observatory in Spain.…
The BlackGEM telescope array I: Overview
Paul J. Groot, S. Bloemen, P. Vreeswijk +75
The main science aim of the BlackGEM array is to detect optical counterparts to gravitational wave mergers. Additionally, the array will perform a set of synoptic surveys to detect…
PLC-controlled cryostats for the BlackGEM and MeerLICHT detectors
Gert Raskin, Johan Morren, Wim Pessemier +5
BlackGEM (BG) is an array of telescopes, currently under development at the Radboud University Nijmegen and at NOVA. It targets the detection of the optical counterparts of gravita…
Binary central stars of planetary nebulae with long orbits: the radial velocity orbit of BD+33.2642 (PN G052.7+50.7) and the orbital motion of HD112313 (PN LoTr5)
Hans Van Winckel, Alain Jorissen, Katrina Exter +4
We study the impact of binary interaction processes on the evolution of low- and intermediate-mass stars using long-term monitoring of their radial velocity. Here we report on our…
Large Frame-Transfer Detectors for the MAIA Imager
Jesús Pérez Padilla, Simon Tulloch, Gert Raskin +4
MAIA, the Mercator Advanced Imager for Asteroseismology, is a new fast-cadence 3-channel photometric instrument. It is installed on the 1.2-m Mercator telescope at the Roque de Los…
Compact Stirling cooling of astronomical detectors
Gert Raskin, Johan Morren, Wim Pessemier +2
MAIA, a three-channel imager targeting fast cadence photometry, was recently installed on the Mercator telescope (La Palma, Spain). This instrument observes a 9.4 x 14.1 arcmin fie…
A practical approach to ontology-enabled control systems for astronomical instrumentation
Wim Pessemier, Gert Raskin, Hans Van Winckel +2
Even though modern service-oriented and data-oriented architectures promise to deliver loosely coupled control systems, they are inherently brittle as they commonly depend on a pri…
MAIA, a three-channel imager for asteroseismology: instrument design
Gert Raskin, Steven Bloemen, Johan Morren +8
MAIA, an acronym for Mercator Advanced Imager for Asteroseismology, is a three-channel instrument that targets fast-cadence three-colour photometry, installed at the 1.2-m Mercator…
Modelling the asymmetric wind of the luminous blue variable binary MWC 314
A. Lobel, J. H. Groh, C. Martayan +12
We present a spectroscopic analysis of MWC 314, a luminous blue variable (LBV) candidate with an extended bipolar nebula. The detailed spectroscopic variability is investigated to…
Chemical surface inhomogeneities in late B-type stars with Hg and Mn peculiarity I Spot evolution in HD 11753 on short and long time scales
H. Korhonen, J. F. Gonzalez, M. Briquet +7
Aims: Time series of high-resolution spectra of the late B-type star HD 11753 exhibiting HgMn chemical peculiarity are used to study the surface distribution of different chemical…
Time resolved spectroscopy of BD+46 442: gas streams and jet creation in a newly discovered evolved binary with a disk
N. Gorlova, H. Van Winckel, C. Gielen +9
Previous studies have shown that many post-AGB stars with dusty disks are associated with single-lined binary stars. To verify the binarity hypothesis on a larger sample, we starte…
Mass ratio from Doppler beaming and Rømer delay versus ellipsoidal modulation in the Kepler data of KOI-74
S. Bloemen, T. R. Marsh, P. Degroote +18
We present a light curve analysis and radial velocity study of KOI-74, an eclipsing A star + white dwarf binary with a 5.2 day orbit. Aside from new spectroscopy covering the orbit…
Modeling the Asymmetric Wind of Massive LBV Binary MWC 314
A. Lobel, J. Groh, K. Torres Dozinel +13
Spectroscopic monitoring with Mercator-HERMES over the past two years reveals that MWC 314 is a massive binary system composed of an early B-type primary LBV star and a less-lumino…
The evolutionary state of Miras with changing pulsation periods
Stefan Uttenthaler, Koen Van Stiphout, Kevin Voet +12
Context: Miras are long-period variables thought to be in the asymptotic giant branch (AGB) phase of evolution. In about one percent of known Miras, the pulsation period is changin…
Chemically tagging the Hyades stream: Does it partly originate from the Hyades cluster?
L. Pompéia, T. Masseron, B. Famaey +19
The Hyades stream has long been thought to be a dispersed vestige of the Hyades cluster. However, recent analyses of the parallax distribution, of the mass function, and of the act…
HERMES: a high-resolution fibre-fed spectrograph for the Mercator telescope
Gert Raskin, Hans Van Winckel, Herman Hensberge +18
The HERMES high-resolution spectrograph project aims at exploiting the specific potential of small but flexible telescopes in observational astrophysics. The optimised optical desi…
