COMMISSIONS AND OF THE IAU INFORMATION BULLETIN ON VARIABLE STARS Number Konkoly Observatory Budap est April HU ISSN THE rd NAMELIST OF VARIABLE STARS The present rd NameList of Variable Stars compiled basically in the manner rst introduced in the th NameList IBVS No contains all data necessary for identication of new variables nally designated in The total number of designated variable stars not counting designated nonexisting stars or stars subsequently identied with earlierdesignated variables has now reached In the nearest future we are going to present two sp ecial NameLists containing variables discovered by the HIPPARCOS mission and in the frame of the OGLE pro ject The rd NameList consists of two tables Table contains the list of new variables arranged in the order of their right ascensions It gives the ordinal number and the des ignation of each variable its equatorial co ordinates for the equinox note that we have changed the standard accuracy For all stars but two we present right ascensions s 00 to and declinations to The co ordinates were found in the literature taken from p ositional catalogues including GSC or determined by the authors Sometimes the ac curacy may actually b e ab out seconds of arc For V and V Cas we could not improve the published rough co ordinates b ecause nding charts are not available the range of variability sometimes the column Min gives in parentheses the amplitude of light variation and the system of magnitudes used the symbols Rc Ic desig nate magnitudes in Cousinss RI system the symbols y b u mean Stromgrens y b u magnitudes g designates magnitudes in the system of Thuan and Gunn T stands for broadband Tycho magnitudes formed from B and V measurements r are red magnitudes not tied to a particular system the type of variability according to the classication system describ ed in the forewords to the rst three volumes of the th GCVS edition with the additions introduced in the th NameList IBVS No in the th NameList IBVS No and in the nd NameList IBVS No two references to the list of pap ers which follows Table the rst reference is to the investigation of the star the second one indicates the pap er containing a nding chart or the corresp onding Durchmusterung BD CoD or CPD containing the variable or the Hubble Space Telescope Guide Star Catalog GSC if the star can b e found using it In a small number of cases the value of the variability amplitude column Min in parentheses could not b e expressed in the same system of magnitudes as the stars brightness in such cases we indicate the photometric band for the amplitude separately Table contains the list of variables arranged in the order of their variable star names within constellations After the designation of a variable its ordinal number from Ta ble is given as well as identications with several ma jor catalogues and identications necessary to nd this star in the pap ers with the rst or indep endent announcement of the discovery of its variability References to such pap ers are given in square brackets af ter the corresp onding identication The name of the discoverer accompanies the reference only in the case of its b eing dierent from the name of the authors of the pap er referred to For the stars having NSV catalogue numbers the references to discovery pap ers already taken into account in the NSV catalogue are not always given After the identi cations some minimal remarks are given if necessary Several new corrections to earlier NameLists have b een found necessary Thus in the NameList No IBVS No V Oph is actually V Oph this was not revealed b ecause of the thenadopted co ordinates for V Oph b eing seriously in error The same applies to V Lyr NameList No IBVS No actually the star is identical with BI Lyr Co ordinates for several stars in the NameLists Nos opcit IBVS No IBVS No are for dierent reasons in error The table b elow contains a list of these stars with corrected co ordinates No Star : : h m s 0 V Sco V Sco V Sco V Sco V Oph AO Lyn V Cyg V Mon V Sgr The following signicant identications are to b e added to the NameLists Nos and PZ And BD V Aql HD K Leo Gliese V Ori AFGL V Sgr NSV V Sgr NSV V Sgr NSV Several more corrections to NameList No V Cyg should have the variability range to P type SR V Oph the magnitudes quoted are in the V band V Pup NSV not Note that the corrected version of the past NameLists in the form of a combined NameList Nos is available as a zip le from Sternberg Astronomical Institute ftp neptunsaimsusu cd pubgroupsclustergcvs Thanks are due to SV Antipin OV
