KKR 18: A Late Arrival Galaxy?
R. Brent Tully, Valentina E. Karachentseva, Igor D. Karachentsev +8
KKR 18 is a dwarf irregular galaxy in the Local Void at a distance of 9.46 Mpc. It is gas rich and was experiencing vigorous star formation 20 - 100 Myr ago. Its metallicity is 4%…
On variability of DDO68-V1, a unique extremely metal-poor LBV
S. A. Pustilnik, Y. A. Perepelitsyna
DDO68-V1 is a Luminous Blue Variable (LBV) star in the eXtremely Metal-Poor (XMP) galaxy DDO68. It resides in the HII region with 12+log(O/H)~7.1 dex, or Z ~ Zo/40. Since DDO68-V1…
Monitoring of DDO68 'Northern Ring' SF regions during years 2016-2023
S. A. Pustilnik, Y. A. Perepelitsyna, A. S. Vinokurov +6
DDO68 is a star-forming (SF) dwarf galaxy residing in a nearby void. Its gas metallicity is among the lowest known in the local Universe, with parameter 12+log(O/H) in the range of…
Local Volume dwarf galaxy Cassiopea I. Gas metallicity, extinction and distance
S. A. Pustilnik, A. L. Tepliakova, A. S. Vinokurov
Cas I is a LV dIrr with a wide range of suggested distances. Tikhonov (2019), using the HST images and the TRGB method, places Cas I at D = 1.6+-0.1 Mpc. Besides, he estimates the…
Dwarfs in nearby voids: results of SALT spectroscopy
S. A. Pustilnik, A. Y. Kniazev, A. L. Tepliakova +2
In the framework of the ongoing project, aimed at the systematical studying galaxies in nearby voids, we conducted spectroscopy with the Southern African Large Telescope (SALT) of…
HI Studies of Extremely Metal Poor Dwarfs in Voids -- I
Sushma Kurapati, Simon A. Pustilnik, Evgeniya S. Egorova
We present and discuss the results of the Giant Metrewave Radio Telescope (GMRT) HI 21-cm line mapping for five isolated low-mass (M_bary ~(2--8)*10^7 Mo) eXtremely Metal Poor (XMP…
