  disk population
Judging by the obtained color-magnitude diagrams, we suggest presence of the old disk population (old red giants) of NGC 1569, which extends as far as Field I at ~6 kpc from the galaxy center.
      
The diffuse flux, which correlates well with the radio continuum, is likely to originate from the disk population with age ~2·109 yrs.
      
I have focussed principally on disk population stars, irrespective of spectral type, luminosity class, and age; and have used predictions of source temperatures and variability to distinguish between the various models.
      
One by-product of such a depletion process is the existence of a scattered disk population in transit from the belt to other places, such as the Jupiter zone, the Oort cloud or interstellar space.
      
We apply them to mock data representing the bulge and disk population of the inner region of spiral galaxies.

Hot ultrashort period Cepheid is a type of variable with period ≤0.~d1, amplitude ≥0.~m2, and spectral type A. They form an extended spherical distribution with little concentration to the Galactic plane. They are not only found in globular clusters, but also in moving stellar groups of old disk population. On the colour-magnitude diagram they are situated near and more left than the hotter edge of the Cepheid instability stripe, so their temperature is higher than other types of pulsating variables.

Hot ultrashort period Cepheid is a type of variable with period ≤0.~d1, amplitude ≥0.~m2, and spectral type A. They form an extended spherical distribution with little concentration to the Galactic plane. They are not only found in globular clusters, but also in moving stellar groups of old disk population. On the colour-magnitude diagram they are situated near and more left than the hotter edge of the Cepheid instability stripe, so their temperature is higher than other types of pulsating variables. Known hot Cepheids in globular clusters are v. 65 of ω Cen., v. 11 of M. 56, and k. 1082 of M. 15. All these three clusters are metal deficient, and with an extended spherical distribution in our Galaxy. The absolute magnitude of v. 65 of ω Cen. s + 0.~m82, v. 11 of M. 56, + 0.~m10, k. 1082 of M. 15, + 0.~m09. So on the colour-magni- tude diagram they are near and bluer than the blue edge of the RR Lyr. variable gap, and are as nearly bright as RR Lyr. variables. There is an amplitude gap around 0.~m2 on the period-amplitude diagram of all the known ultrashort period pulsating variables, and the variables with larger am- plitude are divided into three groups by two period gaps. Except the three hot Cepheids in globular clusters as mentioned above, there are nine others in Galactic field. Except one variable with galactic latitude b = + 10°.44, all the other eight of the nice galactic field stars have |b|>20°.00. Three of the nine variables have population Ⅱ characteristics of hither space velocity and metallic line strength parameter ΔS≥2.

热超短周期造父变星的周期≤0.~d1、变幅≥0.~m2、光谱型为A.在银河系中呈延仲球状分布;在银晕星族的球状星团和年老盘族的运动星群中都有.在色星等图上,处于造父不稳定带的左外侧而温度较高,故简称热造父变星.球状星团中超短周期造父变星现知五颗.三颗是热造父变星:半人马ω的V65星(M_v=+0.~m82),M56的V11星(M_v=+0.~m10)和M15的K1082星(M_v=0.~m09)。它们在色星等图上的位置紧邻,亮度和天琴RR型星相近,但色均较蓝.它们都处在银河系中呈延伸球状分布的贫金属星团中.银河系中已知超短周期造父变星的周期变幅图上,有可用0.~m2简示的变幅分布隙,和两条周期分布隙.其中变幅≥0.~m2、周期≤ 0.~d1的-群共九颗,是银河系一般星场的热造父变星.其银纬分布除一颗是b=+10°44′外,余均为|h|>20°.这九颗中的两颗是年老盘族的运动星群的成员,-颗具有空间速度高和金属线强度ΔS≥2的星族Ⅱ星的特点.
