They are added fuel tanks so the aircraft can carry more than the normal amount of fuel ; for example, for longer range, or greater endurance.

All aircraft, not just jets, have shapes as streamlined as possible to enable them to fly faster and use less fuel.
An aircraft creates thrust by sucking in air through it's turbine engines compressing it and spraying in fuel and then a spark is added to ignite the mixture
Propane and LNG, liquid natural gas are two of the most common. Hydrogen and oxygen used by NASA is also stored as pressurized liquid.
If the aircraft is coming into land then the hinged part of the wing called Flaps are lowered to increase the amount of Drag over the wings. If you think of drag as an air-born form of braking then Flaps down means the aircraft the aircraft slows but increases the maneuverability the pilot has over the aircraft. If the aircraft is on the ground then wheel brakes are very useful
Jumbo jets have several fuel tanks. The majority of these fuel tanks are located in the wings of the aircraft. Some aircraft may also have auxiliary tanks in the tail or belly. The Douglas (now Boeing) MD11 has a fuel tank in the Elevator(horizontal tail surface) that is used to balance the aircraft to fly at altitude with less drag.
conformal fuel tanks
Fuel is generally stored in tanks built into the wings.
To utilize the wing space for the fuel,
Where is the fuel tanks located on small planes? Most of the fuel tanks are located in the wings of the aircraft. There is usually the main tanks that are located in the center of the wings and then there are tip tanks, that are located towards the wing tips.
Wings and belly.
In most modern aircraft they are in the wings.
On vehicles with dual tanks, the front tank is the main and the rear tank is the auxiliary. The main fuel balance pump supplies fuel to the fuel injection unit. The low pressure, about 32 kPa (7 psi) fuel balance pump is used only to transfer fuel from the auxiliary tank to the main tank in order to balance the fuel levels in both tanks. As the main tank level drops to about 25 percent below the level in the auxiliary tank, the fuel sender and balance module energizes the fuel pump relay. This pumps the fuel from the auxiliary tank to the main tank. When the level in the main tank reaches a level slightly higher than the level in the auxiliary tank, or the auxiliary tank is empty, the module de-energizes the balance pump relay and fuel pump. Any malfunction in either of the fuel gauge circuits will disable the system and the fuel will not be transferred from the auxiliary fuel tank to the main fuel tank.
Aircraft use three types of fuel tanks using: (1)integral (2)rigid removable (3)bladder.
In the event engine-driven fuel pump fails.
Those are external fuel tanks, which can be dropped from the plane in flight when they run out of fuel, increasing the aircraft's range. They are also usually dropped when entering a dogfight, in order to reduce weight and make the aircraft more aerodynamic.
It's called 'unusable fuel.' The stats in the operation manual will always state the total fuel capacity and unusable fuel. When there are multiple tanks in multiple locations, the unusable fuel in all tanks will be stated.
