<transcript><audio_51> Perdón, sobre el disco estelar. Y la última, que es por exoplanetas. Y a este método, pues, igual que con estrellas eclipsantes,</transcript><transcript><audio_52> el método de tránsito, método de ocultación. Y lo que vemos en la parte de abajo es cómo cambia la curva de luz con los planetas. Se ven súper claros los tránsitos, ¿no? Es decir, bueno, y en la parte de arriba,</transcript><transcript><audio_53> muestra la posición de los planetas conforme la curva de luz. Entonces, justamente podemos ver cuando los dos planetas están completamente</transcript><transcript><audio_54> cuando se oculta uno o se oculta el otro. Obviamente en nuestro eje X nosotros tenemos tiempo, tenemos días y en nuestro eje Y tenemos flujo relativo.</transcript><transcript><audio_55> estamos hablando de nuestro brillo, el brillo de la luz, de la estrella en el visible. Solamente noten la diferencia entre el brillo micrófono</transcript><transcript><audio_56> pueden hacer con un telescopio en la Tierra. De hecho, estas mediciones, estas observaciones, las hizo el telescopio Kepler para tener</transcript><transcript><audio_57> de estrellas variables intrínsecas, les repito, pues hablamos de procesos internos dentro de una estrella, entonces básicamente las podemos clasificar en dos. Una que son estrellas pulsantes,</transcript><transcript><audio_58> Justamente este cambio de luminosidad se debe a que nuestra estrella se expande y se contrae. A esta categoría dependen las estrellas tipo Cepheidas y tipo Lyras.</transcript><transcript><audio_59> hablar de las estrellas efeidas que son como las más famosas y las dirás en algún momento no bueno entonces nos quedamos con que son estrellas pulsantes expanden y se contraen ahorita vamos a hablar un poquito más justamente bueno ahí se observa</transcript><caption><image_60>The image shows a large room with a projector screen in the center. The screen displays a presentation slide with text and graphs. The room has a tiled floor and white walls with a chandelier hanging from the ceiling. There are two flags on either side of the screen, one is the flag of the United Arab Emirates and the other is the national emblem of the country. There is a podium in the foreground and a few people sitting in chairs in front of the projector screen. The overall atmosphere of the room appears to be a conference or presentation.</caption><transcript><audio_61> dibujito muy bonito, cómo una estrella se contrae, se expande y eso, cómo va generando este cambio en su curva de luz. Cuando tenemos una estrella completamente, bueno, no completamente, pero</transcript> on the solar disk sorry about the disk on the stellar disk that is for exoplanets and now this method well, just as with eclipse stars before, the transit method is called the underground method of occultation and what we see in the part  Below is how the light curve changes with the planets, the transits are super clear, no, that is to say, well, and at the top, the position of the planets is shown according to the light curve, so we can just see  when the two planets are completely hidden and when one is hidden or the other is obviously hidden from our x axis we have time we have days and on our axis we already have relative flow this relative flow we are talking about our ball our brightness the brightness of the light of the star in the visible only notice the difference between the these measurements cannot be made with a telescope on Earth in fact these measurements these observations were made by the Kepler telescope to have as when we talk about intrinsic variables of stars intrinsic variables I repeat because we are talking about internal processes within a star so basically we can classify them into two ones that are pulsating stars that precisely this change in luminosity is due to the fact that our star  It expands and contracts to this category depending on the stars' types of feiras and types of liras have heard of the stars and it was ideas that are like the most famous and you will say them at some point they can't so we are left with that they are pulsating stars.  They expand and contract, right now we are going to talk a just well, there you can see good, like a very nice little drawing, how a star contracts, expands, and that is how it generates this change in its light curve when we have a star that is completely good, not completely.
