Optimizing asteroid orbit computation for Gaia with normal points
Muinonen, Karri; Fedorets, Grigori; Granvik, Mikael +11 more
Context. In addition to the systematic observations of known solar-system objects (SSOs), a continuous processing of new discoveries requiring fast responses is implemented as the short-term processing of Gaia SSO observations, providing alerts for ground-based follow-up observers. The common independent observation approach for the purposes of or…
Multiwavelength approach to classifying transient events in the direction of M 31
Kong, Albert K. H.; Kupfer, Thomas; Laher, Russ R. +4 more
Context. In the hunt for rare time-domain events, it is important to consider confusing exotic extragalactic phenomena with more common Galactic foreground events.
Aims: We show how observations from multiple wavebands, in this case optical and X-ray observations, can be used to facilitate the distinction between the two.
Methods: We dis…
A search for OB stars in the field of the galactic OB association Bochum 7. II. Proper motion and IR photometry
Orellana, R. B.; Corti, M. A.; Bosch, G. L.
Aims: We plan to identify the members of the Bochum 7 association by performing simultaneous astrometric and spectrophotometric analyses, and estimate its distance and evolutionary stage.
Methods: We used our own visual spectroscopic and UBV photometric data of a 30' × 30' region centered at = 8h44m47.2s,…

Parameters and models of the jets from Sanduleak's star in the LMC
Raga, A. C.; Noriega-Crespo, A.; Camps-Fariña, A.
Context. Angeloni and collaborators have discovered a bipolar jet extending out to 6 pc from "Sanduleak's star" in the Large Magellanic Cloud (LMC). This is the first angularly resolved stellar jet system that has been observed outside our Galaxy.
Aims: In this paper we use archival Hubble Space Telescope (HST) images of this jet in order to …
Spectroscopic EUV observations of impulsive solar energetic particle event sources
Innes, D. E.; Fludra, A.; Gómez-Herrero, R. +4 more
Context. Remote observations of solar flare ion acceleration are rather limited. Theoretical predictions for signatures of ion acceleration in extreme ultraviolet (EUV) line profiles have been made. Previous tests involve observations of flares with no evidence for energetic ions.
Aims: We aim to examine a source flare of impulsive (or 3…
Pseudo-photometric distances of 30 open clusters
Duvert, G.; Chelli, A.
Aims: We demonstrate that reliable photometric distances of stellar clusters, and more generally of stars, can be obtained using pseudomagnitudes and rough spectral type without having to correct for visual absorption.
Methods: We determine the mean absolute pseudomagnitude of all spectral (sub)types between B and K. Distances are comput…
Probing the nature of AX J0043-737: Not an 87 ms pulsar in the Small Magellanic Cloud
Haberl, F.; Tiengo, A.; Filipović, M. D. +4 more
Aims: AX J0043-737 is a source in the ASCA catalogue whose nature is uncertain. It is most commonly classified as a Crab-like pulsar in the Small Magellanic Cloud (SMC) following apparent detection of pulsations at 87 ms from a single ASCA observation. A follow-up ASCA observation was not able to confirm this, and the X-ray detection of the s…
