Abstract
We have made an asteroseismic analysis of the variable blue stragglers in the open cluster M67. The data set consists of photometric time‐series from eight sites using nine 0.6–2.1 m telescopes with a time‐baseline of 43 d. In two stars, EW Cnc and EX Cnc, we detect the highest number of frequencies (41 and 26) detected in δ Scuti stars belonging to a stellar cluster, and EW Cnc has the second highest number of frequencies detected in any δ Scuti star. We have computed a grid of pulsation models that take the effects of rotation into account. The distribution of observed and theoretical frequencies shows that in a wide frequency range a significant fraction of the radial and non‐radial low‐degree modes are excited to detectable amplitudes. Despite the large number of observed frequencies we cannot constrain the fundamental parameters of the stars. To make progress we need to identify the degrees of some of the modes from either multicolour photometry or spectroscopy.

stragglers in the open cluster M67. The data set consists of photometric time‐series from eight sites using nine 0.6–2.1 m telescopes with a time‐baseline of 43 d. In two stars, EW Cnc and EX Cnc, we detect the highest number of frequencies (41 and 26) detected in δ Scuti stars belonging to a stellar cluster, and EW Cnc has the second highest number of frequencies detected in any δ Scuti star. We have computed a grid of pulsation models that take the effects of rotation into account. The distribution of observed and theoretical frequencies shows that in a wide frequency range a significant fraction of the radial and non‐radial low‐degree modes are excited to detectable amplitudes. Despite the large number of observed frequencies we cannot constrain the fundamental parameters of the stars. To make progress we need to identify the degrees of some of the modes from either multicolour photometry or spectroscopy.</div></front></TEI><istex><corpusName>wiley</corpusName><keywords><teeft><json:string>scuti</json:string><json:string>mnras</json:string><json:string>gilliland</json:string><json:string>photometric</json:string><json:string>outlier</json:string><json:string>amplitude

The distribution of observed and theoretical frequencies shows that in a wide frequency range a significant fraction of the radial and non‐radial low‐degree modes are excited to detectable amplitudes. Despite the large number of observed frequencies we cannot constrain the fundamental parameters of the stars. To make progress we need to identify the degrees of some of the modes from either multicolour photometry or spectroscopy.</abstract><subject lang="en"><genre>keywords</genre><topic>blue stragglers</topic><topic>stars: individual: EX Cnc</topic><topic>stars: individual: EW Cnc</topic><topic>δ Scuti</topic><topic>open clusters and associations: individual: M67 (NGC 2682)</topic></subject><relatedItem type="host"><titleInfo><title>Monthly Notices of the Royal Astronomical Society</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><identifier type="ISSN">0035-8711</identifier><identifier type="eISSN">1365-2966</identifier><identifier type="DOI">10.1111/(ISSN)1365-2966</identifier><identifier type="PublisherID">MNR</identifier><part><date>2007</date><detail type="volume"><caption>vol.</caption><number>378</number></detail><detail type="issue"><caption>no.</caption><number>4</number></detail><extent unit="pages"><start>1371</start><end>1384</end><total>14</total></extent></part></relatedItem><identifier type="istex">E314D55C11BF66413069810356782E82066B0662</identifier><identifier type="ark">ark:/67375/WNG-W51N5RKQ-S</identifier><identifier type="DOI">10.1111/j.1365-2966.2007.11865.x</identifier><identifier type="ArticleID">MNR11865</identifier><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-L0C46X92-X">wiley</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/document/E314D55C11BF66413069810356782E82066B0662/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
