When I watched the story about the difficulties to find an object around other stars I started to think in alterinatives that could exist to make the object larger.
The presented alternatives will reduce the amount of objects that can be found but can help to find more easy some planets.
Below I will list in descending order of size:
1) If the planet has a magnetosphere then this is a giant gas planet or if is rocky planet that have an active nucleus (The Jupiter Magnetosphere is almost the same size of sun).
Collisions between the star wind and the planet's magnetosphere will create distortions in the solar disc represented by variation in the star wind temperature. The most critical would be: what is the best range of infrared to look? And the instruments that have sensitivity for picking up the distortions in the halo temperature.
2) In the case to search for planets with Ionosphere of exoplanet the biggest problem would be our planet, because it reflects the biggest portion of HF signal in the range of 20 to 30 Mhz, then how could we receive a signal in this bandwith reflected by a planet from a distant star?
Only if our antena is in orbit above our ionosphere may be a good idea. Or if we have a excelent Antena on ground to capture some signal that is not filtered by our ionosphere. There is another key point will be necessary a computer program that must save all data (from 6-15 minutes FIFO data according to kind of star) and compare if this signal was reflected by planet from its star or if this an event in the planet atmosphere that can produce signals in this bandwith.
3) In the case to search planets by UV reflection this is more specific and we are looking for planets with a possible ozone layer, the alternative would be to compare with the absorption of infrared. But by using only one recpetor in the UV bandwidth may be an option if we compare the difference between UV -A and UV-B. If the atmosphere has an oxygen-ozone cycle, UV-B range would absorbed by process when compared with UV-A.
All these alternatives are limiting the search for exoplanets but if we find some of them via one of these methods would be incredible because:
- If the planet has Magnetosphere, its core is active.
- If he has a Ionosphere, it has a complex amosfera.
- If it reflects UV-A whilie absorbing UV-B it is posible existence of an oxigen - ozone cycle.
- If it absorbs more infrared and reflects the UV-A then it has a greenhouse effect with a possible cycle of oxygen-oxonio. (Something very interesting).
