VB2019 Simultion of our Galagy, including sagitarius and 10 mini Black holes

Introduction and Purpose

The purpose of the program "VB Sagittarius" is to simulate the black hole Sagittarius A* and 10 mini BH's:

  3. https://en.wikipedia.org/wiki/S2_(star)
This program is part of what is called the "Sagitarrius Project". To read more select this link Sagittarius Project
Temporary important is this: Carpe Diem and Sagittarius.
Please study that document in relation with Display 2, shown below, and observe that the w parameter changes when Display 2 is selected or not selected. The same is true for inclination. The omega parameter is constant, which it should not.


Program Description

The program consists of 4 Forms: Control, Display, Menu and Figure
  1. The Control Form is used to select a planet simulation and to perform a simulation.
  2. The Display Form shows the results of a simultion and the result of a simulation saved in a Data Bae
  3. The Menu Form is to select additional parameters used by a planet simulation
  4. The Figure Form is to select a simulation saved in a Data Base

Control Form - Operation

Display 1
The control form is used to select and perform a simulation.
  1. First select a particular simulation to be performed.
    In the example this is simulation 7, which demonstrates "Sagittarius and 10 Mini BH's"
  2. Next Select "Parameter Selection Menu" in order to change cetain parameters relevant for this simulation. This is an option.
  3. Next Select Start
  4. Next the simulation will show the Display Form as shown in Display 2. An additinal display shows the evolution of the simulation.See Display 3.
The control form is also use to create a certain number of predefined figures.
This option is currently not available.
  1. First select a particular figure to be created.
    Select Menu Selection Form. Select SubTest and return back to control form
  2. Next Select Start
  3. Next the simulation will show the Display Form as shown in Figure 2

The Display Form is divided in 5 parts
  1. A top header section which shows general information.
  2. A top box left showing information about 10 mini BH's
  3. A top box right showing information about 10 mini BH's
  4. A bottum box left showing information about 10 mini BH's
  5. A bottum box right showing specific information about mini BH 1. This infomation is related to the first line of each of the other 3 Boxes.
Now we go to something more specific data.

Display 3b
Both Display 3a and 3b show the same situation. The situation enlarged with a factor 2.
The most remarqueble chance is in the star S62, in green. Also interesting is the star S2. What is observed is the mutual influence between the 10 stars or 10 mini Black Holes.
The simulation is solely done using Newton's law.
