[ITAL]BV[/ITAL] Photometry of Variable Stars in the Northeast Arm of the Small Magellanic Cloud

B and V photometry has been obtained for variable stars in the northeast armof the Small Magellanic Cloud (SMC). Periods and lightcurves have beendetermined for 237 periodic variables, including 201 Cepheids, 68 of which arenewly discovered. Fundamental mode Cepheids and first overtone mode Cepheidsare generally well separated in the B,V color-magnitude diagram, with thelatter having bluer mean colors than the former. The Cepheid period-colorrelationship for this outlying SMC field is indistinguishable from that seen inmore centrally located SMC fields, and is bluer than theoretical predictions.The red edge to the populated portion of the instability strip shifts to bluercolors for fainter Cepheids. There is support from our sample for a previouslyreported steepening in the slope of the period-luminosity relation forfundamental mode Cepheids near a period of 2 days. The Cepheids of thenortheast arm may be closer to us than are those of the main body of the SMC,but the difference is smaller than or equal to about 4 kpc, comparable to thetidal radius of the SMC.Comment: 51 pages, 22 figures, AJ, accepted, larger figures 1-3 available at ftp://ftp.pa.msu.edu/pub/smit
