cds-question@unistra.frvariable-starssubdwarf-starsb-starsWe present follow-up observations of the pulsating subdwarf B (sdB) star EC 01541-1409 as part of our efforts to resolve pulsation spectra for use in asteroseismological analyses. This paper reports on data obtained from a single-site campaign, during 2008, and a multisite campaign, during 2009. From limited 2008 data, we were able to clearly resolve and pre-whiten 24 periods. A subsequent multisite campaign spanning nearly 2 months found over 30 individual periodicities most of which were unstable in amplitude and/or phase. Pulsation amplitudes were found to the detection limit, meaning that further observations would likely reveal more periodicities.2012MNRAS.421..181Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/421/181CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/393/965 : Slowly pulsating B stars intrinsic frequencies (de Cat+, 2002)J/A+A/506/143 : Pulsations of HD 181231 (Neiner+, 2009)J/A+A/513/A6 : NOT survey of subdwarf B stars (Ostensen+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/421/181https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/421/181http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/421/181https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/421/181https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/421/181http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/421/181GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/421/181/table2Frequencies and amplitudes for EC 01541 from the 2008 single-site and 2009 multisite campaignsrecnoRecord number assigned by the VizieR team.
